Breitbart News editor-in-chief Alex Marlow sat down with liberal political comedian Bill Maher on his HBO show "Real Time" Friday evening for a one-on-one interview that focused largely on the Russia investigation and free speech.

Marlow explained to Maher that it is "by design" that his conservative website doesn't spend much time covering the several federal and congressional investigations into Russian interference in the 2016 election and possible ties to President Trump's campaign as the vast majority of the media already spends a great deal of time covering that topic. "We cover stories the establishment press does not want to cover," he said.

Marlow explained that he doesn't doubt that Russia "wants to sow discord in the United States," and accepts the intelligence community believes that Russia did meddle in the election process. But, he said, "there is no hard evidence of collusion," and that if and when there is, "then we can have the impeachment conversation."

The editor also decried "cowardly people" who are putting out misinformation about Breitbart News and rounding up boycotts against the website. Acknowledging that this is happening now on both sides of the political spectrum, Marlow called on a united front to stop any infringement on free speech.

"People on the left and the right who are free speech advocates need to come together right now and say the corporations are not going to define the first Amendment and free speech in this country," Marlow said to applause.

Upon starting the interview, Maher complimented Marlow for having the "balls" to come on his show, lamented that "I can't get Democrats to come here."

Marlow, in turn, thanked Maher for giving him a chance to explain the conservative side of the political debate, which he says is espoused by his website.

"I think that a lot of our inspiration at Breitbart has been following Democrats and people on the left over the years," Marlow said. "I'm from Los Angeles, I went to Berkeley, I witness, I live in Washington, D.C., and watching the Left fight effectively, fight tooth and nail for their values, that's what Breitbart was founded on. Those principals that we believe what we believe so we're going to fight for them with all we have."

"Oh wow. I didn't expect you to say that," was Maher's response. Maher also complimented Breitbart for being honest about being a right-wing organization where Fox News will not.

While the majority of the conversation was civil, the two didn't agree on everything, notably on Breitbart's lack of coverage on the Russia issue.
