House Oversight Committee ranking member Rep. Elijah Cummings (D-MD) on his grilling of GSA official Jeff Neely in Monday's hearing.

For the first time since the GSA spending scandal broke, we'll be hearing from the woman who blew the whistle on the agency's lavish conference which cost taxpayers more than $800,000.

In just a few hours, the House Transportation and Infrastructure Committee will be holding the second of four Congressional hearings looking into the matter. On Monday, the House Oversight Committee held its hearing on the matter.

One of the toughest exchanges was between Congressman Jason Chaffetz (R-UT_ and former GSA Administrator Martha Johnson, who resigned over the scandal.

"I think that is the fundamental problem that America gets and that government doesn't get," Chaffetz says. "There are a lot of good federal employees that work hard. They're patriotic and they're frugal with their money. But when you see this widespread abuse of money and then you, as the former administrator, says, 'Well, they're entitled to it.' That's where there is frustration just steaming out of our ears."

This morning on "Starting Point," Rep. John Mica (R-FL), head of the House Transportation and Infrastructure Committee, previews today's hearing on the GSA scandal and alludes to a possible cover up by the White House.

"We're going to look at the sequence of when things happened," Mica says. "Looks like Susan Brita [GSA deputy administrator] did go...as soon as she heard about it she went to the inspector general and proper authorities. People from the White House knew about it, did nothing, kept it quiet until just a few days ago when a statement was released by the President condemning the act. We think they've held this information."

Roll Call Reporter Jonathan Strong says although the president appoints leadership for federal agency, the GSA’s “culture of corruption” is also responsible.
