Sen. Amy Klobuchar and two Democratic colleagues penned a letter to House Speaker John Boehner today pushing the Ohio Republican for repeal of an unpopular tax-reporting requirement for businesses under the new health care law. Fresh on the heels of the 245-189 House vote to repeal President Obama's health care overhaul, the Minnesota DFLer is seeking common ground on a tweak that might actually gain traction in the Senate, which is still controlled by Democrats. She was joined by Sens. Ben Nelson of Nebraska and Maria Cantwell of Washington State. All three are up for reelection in 2012. The focus of the letter is an IRS provision that requires businesses to file 1099 reports on all purchases of $600 or more. The measure has been widely panned in both parties. "Now that you have moved past repeal of the Affordable Care Act, we encourage you to work on efforts to improve the law moving forward," the senators wrote in a letter to Boehner. Boehner spokesman Michael Steel told the Washington Post that Republican leaders support the 1099 repeal but emphasized that their top priority is repeal of the entire health care law.
