WASHINGTON – U.S. Senator Amy Klobuchar (D-MN), Chairwoman of the Senate Rules Committee with oversight over federal elections and campaign finance law, with Senator John Tester (D-MT) and Senator Ron Wyden (D-OR), led a letter with 36 additional Democratic senators urging the Treasury Department and Internal Revenue Service (IRS) to reverse the Trump Administration’s decision to eliminate disclosure requirements for certain tax-exempt organizations that engage in political activity. The letter to Treasury Secretary Janet Yellen and Internal Revenue Service Commissioner Charles Rettig highlighted how eliminating the requirement that tax-exempt groups disclose the source of their contributions used for political activity undercut efforts to enforce prohibitions against foreign spending in U.S. elections and detect other illegal activity.

The senators stressed that reinstating the rule is a critical step in preventing special interests and foreign actors from exploiting loopholes at the expense of the American people.

“For decades, the Treasury Department and IRS required 501(c)(4) organizations and other tax-exempt groups that are eligible to engage in political advocacy to identify, in confidential filings, the names and addresses of individual donors who make significant financial contributions over $5,000,” the members wrote.

“Reinstating this rule is a critical step in preventing special interests and foreign actors from exploiting loopholes at the expense of the American people. We strongly urge you to reconsider the prior administration’s decision and reinstate the requirement that certain tax-exempt organizations engaged in political activity disclose information about their major donors to the IRS.”

Senators Klobuchar, Tester, and Wyden were joined on the letter by the following 36 senators: Charles E. Schumer (D-NY), Sheldon Whitehouse (D-RI), Sherrod Brown (D-OH), Patrick Leahy (D-VT), Mazie Hirono (D-HI), Jeff Merkley (D-OR), Michael Bennet (D-CO), Bob Casey Jr. (D-PA), Chris Murphy (D-CT), Diane Feinstein (D-CA), Ben Cardin (D-MD), Ed Markey (D-MA), Cory Booker (D-NJ), Dick Durbin (D-IL), Brian Schatz (D-HI), Maggie Hassan (D-NH), Jeanne Shaheen (D-NH), Kristen Gillibrand (D-NY), Tina Smith (D-MN), Ben Ray Lujan (D-NM), Raphael Warnock (D-GA), Elizabeth Warren (D-MA), Alex Padilla (D-CA), Tammy Baldwin (D-WI), Richard Blumenthal (D-CT), Tammy Duckworth (D-IL), Tom Carper (D-DE), Chris Van Hollen (D-MD), Patty Murray (D-WA), Bernie Sanders (D-VT), Tim Kaine (D-VA), Joe Manchin (D-WV), Catherine Cortez Masto (D-NV), Jack Reed (D-RI), Martin Heinrich (D-NM), and Bob Menendez (D-NJ).

Dear Secretary Yellen and Commissioner Rettig:

We write to urge the Treasury Department and Internal Revenue Service (IRS) to reverse the Trump Administration’s decision to eliminate disclosure requirements for certain tax-exempt organizations that engage in political activity. As it stands, this policy weakens federal tax laws, campaign finance laws, and longstanding efforts to prevent foreign interference in U.S. elections. 

For decades, the Treasury Department and IRS required 501(c)(4) organizations and other tax-exempt groups that are eligible to engage in political advocacy to identify, in confidential filings, the names and addresses of individual donors who make significant financial contributions over $5,000. In 2018, the IRS attempted to unilaterally eliminate this requirement. That same year, the Senate voted in a bipartisan manner to overrule the IRS’s action, and the rule was eventually struck down by a Federal court. Despite the Senate vote and Federal court ruling, in May of last year the Treasury Department and IRS finalized a regulation eliminating this longstanding disclosure requirement, allowing 501(c)(4), 501(c)(5) and 501(c)(6) groups engaged in political activity to hide the identities of major donors from the IRS. 

Eliminating the requirement that tax-exempt groups disclose basic information about the source of their contributions undercuts efforts to enforce prohibitions against foreign spending in U.S. elections and detect other illegal activity. It also undermines the ability of the U.S. government to police the wave of “dark money” that has flooded our political system in the decade since the Supreme Court’s decision in Citizens United v. Federal Elections Commission. According to a study by the nonpartisan Center for Responsive Politics, dark money groups have spent over $1 billion to influence U.S. elections since 2008. 

As secret campaign contributions continue to pour into federal elections, this IRS rule is a major step backwards for transparency and will allow dark money to continue to corrode our political system. The IRS needs every tool at its disposal to ensure that these organizations are complying with the law. 

Reinstating this rule is a critical step in preventing special interests and foreign actors from exploiting loopholes at the expense of the American people. We strongly urge you to reconsider the prior administration’s decision and reinstate the requirement that certain tax-exempt organizations engaged in political activity disclose information about their major donors to the IRS.
