House Minority Leader Nancy Pelosi condemned the Internal Revenue Service for targeting conservative groups in a statement Monday, and also used the opportunity to push for campaign finance reform.

“There needs to be more clarity in the law regarding the activities of tax exempt organizations along with greater disclosure and transparency,” Pelosi said in the statement Monday.

“We must overturn Citizens United, which has exacerbated the challenges posed by some of these so-called ‘social welfare’ organizations. And we must take appropriate action, without any delay or hesitation, to ensure that the IRS remains an impartial agency for America’s taxpayers and our nation’s families and businesses,” she added.

The California Democrat has been a big supporter of campaign finance reform measures, such as the DISCLOSE Act, in the past. But the IRS scandal poses a new threat to campaign fiance reform advocates who have been pushing Congress to crack down on the agency for allowing tax-exempt nonprofits to spend hundreds of millions of dollars on political activity.

Pelosi also promised to hold those responsible accountable in her statement.

“While we look forward to reviewing the Inspector General’s report this week, it is clear that the actions taken by some at the IRS must be condemned,” she said.

“Those who engaged in this behavior were wrong and must be held accountable for their actions,” she added. “Regardless of political affiliation or bias, there is no place for this type of activity by the IRS or its employees.”
