“Oh, there’s a slew of them,” said Rep. Patrick Tiberi (R-Ohio), a member of the tax-writing Ways and Means Committee. He said several lawmakers on the panel had been given tips about over-aggressive actions by the IRS.

Tiberi is one of several lawmakers who went public this week with allegations of wider abuses by the IRS. He and the other officials acknowledged the complaints from their constituents could be true or false, and said that they intended to look into the matters.

“I’m certainly going to spend a lot of time looking into it,” said Sen. Tom Coburn, who heard complaints from constituents who claimed they were audited by the IRS after making substantial donations to Mitt Romney’s 2012 presidential campaign.

The complaints come amid a wide-ranging scandal at the IRS, where a government watchdog report found some conservative groups seeking tax-exempt status were subjected to broader scrutiny because of their politics. IRS officials subjected groups with the words “Tea Party,” for example, to heavier scrutiny.
