UPDATE: The House passed the DISCLOSE Act (HR 5175) on Thursday by a vote of 219 to 206.

House Democrats initially planned to pass it last week, but House Speaker Nancy Pelosi (D-CA) had to pull the legislation from the floor and scrap the vote due to backlash and differing opinions over an exemption for the National Rifle Association (NRA). After broad opposition to the exemption for the NRA, changes were made for the exemption to cover more groups.

According to The Hill, "the legislation’s chief sponsor, Rep. Chris Van Hollen (D-Md.), spent the weekend calling House members to try to salvage it. He also spoke with White House Chief of Staff Rahm Emanuel and Sen. Charles Schumer (D-N.Y.), the author of a companion bill in the Senate, said a Democratic aide who described the effort as 'an all-hands-on-deck' attempt to pass the bill."

The aide told The Hill that the hope was that the efforts would result in passing the bill in the House later this week.

The White House confirmed in a released statement earlier this week that it supports the bill, even with the exemptions.

The U.S. Chamber of Commerce released an ad on Monday that is designed to prevent the legislation from reaching the House floor. According to The Hill, the ad contains "an image of the First Amendment with the words 'abridging the freedom of speech' crossed out in red ink."

Congressional aides initially told Roll Call that the "Rules Committee [would] take up the measure Wednesday with floor action likely Thursday."
