The Iowa capitol is currently under lockdown. Sometime before 4 pm this afternoon, State Representative Ako Abdul-Samad’s clerk was opening mail in the Iowa House chamber while House members were debating a bill on banning traffic cameras. One envelope contained white powder and a threatening message. According to a source inside the House chamber, powder got on the clerk, Abdul-Samad, and the carpet. Radio Iowa reported that debate was suspended at 3:47 pm. About an hour later, visitors were asked not to leave the building.

As of 5:30 pm, two yellow-suited hazmat workers are in the House chamber trying to determine whether the white powder is dangerous. Other than Abdul-Samad, who was taken to another room, most of the state representatives are in the chamber, as are many of their clerks and Iowa House Republican and Democratic staff. Some lobbyists are in the House gallery, having taken seats there to watch debate before the lockdown.

UPDATE: Further news on this story is after the jump.

A Polk County District Court judge rejected a lawsuit by the Iowa Farm Bureau Federation and two other industry groups seeking to invalidate the most significant water quality regulations adopted in Iowa during the past decade.

President Barack Obama’s re-election campaign accuses Republican front-runner Mitt Romney of standing with Big Oil in a new television commercial running in Iowa, Colorado, Florida, Nevada, Ohio, and Virginia. The video and transcript of the Obama campaign’s second ad in Iowa are after the jump. It’s a direct response to an anti-Obama spot about high gasoline prices, which is now running in Iowa and other swing states.

The Obama campaign’s first television commercial in Iowa and other swing states focused on energy policy and criticized the “secretive oil billionaires attacking President Obama.”  

Governor Terry Branstad doubled down today in support of lean finely textured beef. Not only is he urging schools to keep using the product, he wants Congress to investigate the “smear campaign” by critics of so-called “pink slime.”

Follow me after the jump for the governor’s latest comments and Senator Chuck Grassley’s more measured defense of lean finely textured beef.

Groups opposing and supporting President Barack Obama’s re-election are making high gas prices the focal point of new television commercials in Iowa and other swing states. Videos and transcripts of the latest ads by the American Energy Alliance and Priorities USA are after the jump.

Last week Obama urged Congress to end tax breaks for oil companies, citing the industry’s high profits. U.S. Senate Republicans filibustered a bill that would have ended several deductions for five major oil companies and extended various renewable energy tax incentives. Senator Tom Harkin voted to move forward with that bill, but Senator Chuck Grassley voted to block it, as he did with similar legislation in May 2011.

Recreation on Iowa rivers generates enough economic activity to support about 6,350 jobs, according to a new study by Iowa State University’s Center for Agricultural and Rural Development.

Unfortunately, a new report by Environment Iowa indicates that this state’s rivers are among the country’s most polluted waterways.

Follow me after the jump for excerpts from both reports, published last week.

What’s on your mind this weekend, Bleeding Heartland readers? I’m catching up on two stories I didn’t have time to write about during the past week: President Barack Obama’s choice of Jim Yong Kim to be next president of the World Bank, and Vice President Joe Biden’s March 28 visits to Davenport and Sioux City. Kim was born in South Korea but grew up in Muscatine, where his family moved when he was five years old. More clips about Kim and Biden’s latest Iowa trip are after the jump.

Sad news from the south side of Des Moines: Cha Cha, the male lion at the Blank Park Zoo, was euthanized this week after being diagnosed with inoperable liver cancer. He was 16 years old.

This is an open thread; all topics welcome.  

Three-term Representative Dave Loebsack’s campaign moved quickly to define primary challenger Joe Seng after a panel confirmed that the state senator had qualified for the ballot in the Democratic primary to represent Iowa’s second Congressional district. A fundraising e-mail from Loebsack’s campaign manager Brian Fritsch on March 29 described Seng as the “Koch Brothers funded Democrat.” I enclose the full text of that e-mail after the jump. Fritsch declared in an e-mail blast last week, “Our primary opponent accepted sizable contributions from Koch Industries in the past, the corporation owed and operated by the Koch brothers. This makes my stomach turn.”

I didn’t find any Koch contributions listed on Seng’s two latest fundraising reports. During the 2010 campaign, he received two checks for $500 each from the Koch Industries PAC. That’s not a lot of money, but Seng doesn’t have many donors aside from political action committees that give to most Iowa legislators. Overall, he raises surprisingly little for an entrenched incumbent. I didn’t see any Koch contributions in Seng’s campaign finance reports from 2004 through 2009.

Any comments about the IA-02 race are welcome in this thread.

With two days to spare before authorization for federal transportation programs and the gasoline tax expires, the U.S. House approved a 90-day extension bill Thursday instead of taking up the long-term transportation bill approved with bipartisan support in the U.S. Senate. All five House members from Iowa were among the 229 Republicans and 37 Democrats who voted for the short-term bill. Ten Republicans and 148 Democrats voted no. After the jump I’ve posted comments about today’s vote from Representatives Dave Loebsack (D, IA-02) and Steve King (R, IA-05), along with statements Leonard Boswell (D, IA-03) and Bruce Braley (D, IA-01) released last week. I’ll update the post if Tom Latham (R, IA-04) comments on the transportation policy impasse.

The Senate approved the bill by voice vote Thursday to send it to the president’s desk before March 31. Several Democrats criticized House Republicans for not passing the Senate bill or a House version of long-term legislation, which would prompt conference committee negotiations. Both Chuck Grassley and Tom Harkin voted for the Senate version of the highway bill two weeks ago.

Democratic opponents of a bill designed to promote nuclear power in Iowa have drafted a dozen amendments to House file 561, in case the bill comes up for debate in the Iowa Senate. The bill squeaked through the Iowa Senate Commerce Committee earlier this month. After the jump I’ve posted summaries of the proposed amendments, which would strengthen consumer protections and possibly deter MidAmerican Energy from pursuing a new nuclear reactor project.

State Senator Joe Seng caught a lucky break yesterday when a three-member panel agreed that he qualified for the ballot in the Democratic primary to represent Iowa’s second Congressional district.

I can’t believe how early wildflowers are blooming in central Iowa this year, especially compared to the unusually cold spring of 2011. After the jump I’ve posted a few photos of Dutchman’s breeches, which are common in wooded areas.

This is a mid-week open thread: all topics welcome.

Iowa politicians from both parties are speaking out today in defense of finely textured beef product, now commonly known as “pink slime.” The U.S. Department of Agriculture announced earlier this month that it will give schools the option of buying ground beef that does not contain the product. Several grocery store chains have recently announced that they will stop carrying ground beef containing the product, prompting Beef Products Inc. to suspend production of finely textured beef product at three plants for 60 days. One of the closed plants is in Waterloo. BPI is leaving its plant in South Sioux City, Nebraska running for now.

Iowa political reaction to the controversy is after the jump.

The nice thing about a large majority, like the 60 to 40 Republican advantage in the Iowa House, is not needing every vote in your caucus for every bill. Members can oppose the party line when local interests are threatened without derailing the legislative process. Retiring State Representative Steve Lukan showed how it’s done when he voted against the Rebuild Iowa Infrastructure Fund budget in the House Appropriations Committee last week, because that bill left out $5 million in funding for a major project in Lukan’s district.

This basic concept of representing your constituents is apparently lost on Walt Rogers. The first-term Republican from a district covering parts of Cedar Falls and Waterloo just voted for an education budget that slashes funding for the University of Northern Iowa.

UPDATE: Scroll down for Rogers’ weekly newsletter, which discusses his vote on the education budget.

Democrats Bruce Braley (IA-01), Dave Loebsack (IA-02), and Leonard Boswell (IA-03) joined Republicans Tom Latham (IA-04) and Steve King (IA-05) in voting yesterday for the Senate version of a bill designed to help small business start-ups. The five representatives all supported the original version of the bill earlier this month. Republican Chuck Grassley also voted for the bill when it came before the Senate last week, but Democrat Tom Harkin opposed it over concerns it would further deregulate Wall Street and undermine investor protections. After yesterday’s vote, Braley hailed the bipartisan action to “reduce small business restrictions,” while Loebsack highlighted provisions he advocated to promote small businesses owned by womens, veterans, and minorities. I enclose those statements at the end of this post.

Also on March 27, the U.S. House approved a bill designed to weaken the Federal Communications Commission’s ability to regulate. Iowans split on party lines. Follow me after the jump for details on that bill and various amendments debated on the House floor yesterday.

At least 200 people gathered on the west steps of the Iowa State Capitol Monday evening for a rally and vigil marking one month since Trayvon Martin’s killing in Floriday. After the jump I’ve posted a few notes from the event, along with links about the impact of Martin’s death on the debate over proposed “stand your ground” legislation in Iowa.

Most bills that lack bipartisan support in the U.S. Senate die by filibuster, but senators voted overwhelmingly yesterday to move forward with debate on a bill that would end tax breaks for oil companies.  

Friday marked the second anniversary of President Barack Obama signing the Patient Protection and Affordable Care Act, more commonly known as health care reform or “Obamacare.” After the jump I enclose lots of news related to the milestone, including comments from Iowa elected officials and statistics on how certain provisions affect Iowans.

This morning the U.S. Supreme Court is scheduled to start hearing oral arguments regarding the constitutionality of the health care reform law. Governor Terry Branstad signed Iowa on to one of the lawsuits challenging the Affordable Care Act last year. Near the end of this post I’ve included some speculation about how the justices may rule (or punt).

What’s on your mind this weekend, Bleeding Heartland readers? Hope you are enjoying the unseasonably warm spring weather.

Mitt Romney may be the least-liked presidential front-runner ever among the Republican base, but he seems to have a lock on the GOP nomination. Despite losing the Louisiana primary convincingly to Rick Santorum yesterday, Romney has nearly half of the 1,144 delegates needed to secure the nomination. Santorum has fewer than half as many delegates, and only 21 states plus Washington, DC have yet to vote.

Someone has challenged the nominating petitions filed by State Senator Joe Seng, who is running against Representative Dave Loebsack in the second Congressional district primary.

Details are after the jump, along with the first e-mail blast from Loebsack’s campaign that discussed the primary challenge.
