(NBCNC) - It's going to be another rough day for the Internal Revenue Service.
Today, the IRS is bracing for a one-two punch here in Washington, "It seems we have a new misstep every day at the IRS," said Rep. Hal Rogers, (R) Kentucky.
For the Internal Revenue Service, it's another day in the hot seat on Capitol Hill.
An Inspector General's report out today reveals show how the agency spent, and misspent, some of the tax dollars it collected, "I certainly plan on holding people accountable," said Daniel Werfel, IRS Acting Commissioner.
The agency's acting chief promised the IRS has already changed course.
Back in 2010, an investigation has found that the agency spent 49 million dollars on travel and training.
For one conference alone, it doled out $135,000 dollars for speakers, including $11,000 for a happiness expert.
But lawmakers still have questions about the agency's singling out of conservative groups. "I am furious that the IRS engaged in ideological scrutiny, which is absolutely unacceptable," said Rep. Nita Lowey, (D) New York.
Those conservative groups get to tell their side of the story today. "And you're gonna hear their outrage, you know how hurtful it was to them to feel like their group was being targeted, like they were being targeted," said Whitney Neal, Freedom Works.
A taxing week for the IRS, and it's not over yet.
