A huge majority of Americans don't believe the Internal Revenue Service accidentally lost thousands of emails tied to a congressional probe of the agency's targeting of Tea Party and other conservative groups.
The emails belonged to former IRS official Lois Lerner, who's at the heart of the investigation.
House lawmakers have accused the tax agency of stonewalling.
"They've not only not fully cooperated, they haven't done a thing to help us get to the truth of what really happened," House Speaker John Boehner, R-Ohio, said. "Lois Lerner refuses to tell us the truth, and then all of sudden, 'Oh my goodness, we lose two years' worth emails.' Listen, I grew up in a bar. This doesn't pass the straight-face test."
But on Monday, IRS Commissioner John Koskinen brushed aside those charges.
"I didn't come out of retirement to play games," Koskinen told reporters Monday, following a House Oversight Committee hearing. "I came out of retirement to restore the credibility of the IRS."
However, according to a new Fox News poll, most Americans share lawmakers' skepticism.
The survey shows 76 percent believe the emails were deliberately destroyed, while only 12 percent believe it was an accident.
And 74 percent say lawmakers should investigate, "until someone is held accountable."
