MSNBC's Morning Joe host Mika Brzezinski accused former Mayor Rudy Giuliani of coming on the show last week to "vomit out complete, baseless lies."

Appearing on the show last Thursday, Giuliani claimed that the Obama administration had not talked with oil industry experts about how to stop the leaking well.

But Brzezinski said Monday the former New York mayor did not have his  facts straight and initially left the hosts "stunned."

"I'm glad there’s someone on the set who is actually asking questions when people come and vomit out complete and baseless lies on our set," Brzezinski said of herself. "I’m sorry but that was so over the top, and we sat there like stunned in silence because it was so untrue because we could not believe it."

She added, "But it was not true."

On Thursday Giuliani said Obama's handling of the crisis was inept.

“If Bush were the president and he handled it this way, there would be a movement to throw him out of office," he said.

But Brzezinski fired back Monday morning, saying that Giuliani wanted to simply "blather on about narratives."

“I did ask the White House for information on who they met with and when,” she said. “It's called asking questions.”

Still, Brzezinski's defense of Obama came under fire for being one-sided when co-host Joe Scarborough alluded to a file of "talking points" on the set supplied by administration officials, according to

"Do you want to know why I have a file that I have been working on with the White House?" she asked guest and former General Electric CEO Jack Welch. "Because of your friend Rudy Giuliani who came on here last week spewing out a whole bunch of nothing."
