Crowley: DNC Email Leak Supports Trump's Argument That 'System Is Rigged'

TUNE IN: 'Fox News Reporting' Examines Hillary Clinton's 'Left Turn'

Hillary Clinton's choice of the centrist Virginia Sen. Tim Kaine as her running mate comes at a time when she faces a new potential problem with the left over today's release of 19,000 Democratic National Committee emails by Wikileaks.

Tonight on The O'Reilly Factor, James Rosen called Wikileaks' timing on the eve of the Democratic convention "amazing," adding that the trove of emails is "somewhat damaging" for Clinton.

"They tend to validate what Bernie Sanders has been saying all along. He has been complaining about Debbie Wasserman Schultz...being tilted and trying to slant the entire process in favor of Hillary Clinton all along."

Rosen said that Clinton has long faced an "enthusiasm gap" with the left and that Kaine won't be able to solve that problem for her.

"Just the sound of it: 'Clinton-Kaine.' It's not exactly stirring," he added.

Brit Hume said there's "nothing abrasive" about Kaine, saying that the Virginia senator should serve her well.

"If she hasn't got her left flank protected by now, she's not going to get it by virtue of this pick," he said.
