Joe Biden's campaign demands major news outlets stop booking Rudy Giuliani to speak about Ukraine

Joe Biden's presidential campaign has sent a letter to major cable news networks and top anchors demanding they stop inviting Rudy Giuliani, the personal lawyer of President Donald Trump, on their programs.

The letter, sent on official Biden campaign letterhead, claims Giuliani is using the major news networks to spread "conspiracy theories" and "advance his own narrative."

"We are writing today with grave concern that you continue to book Rudy Giuliani on your air to spread false, debunked conspiracy theories on behalf of Donald Trump," the letter says.

"While you often factcheck his statements in real time during your discussions, that is no longer enough. By giving him your air time, you are allowing him to introduce increasingly unhinged, unfounded and desperate lies into the national conversation," the letter adds.

It continues, "We write to demand that in service to the facts, you no longer book Rudy Giuliani, a surrogate for Donald Trump who has demonstrated that he will knowingly and willingly lie in order to advance his own narrative."

"Giving Rudy Giuliani valuable time on your air to push these lies in the first place is a disservice to your audience and a disservice to journalism. We ask that you no longer book him on your air," the letter concludes.

The letter was sent by Anita Dunn, a senior adviser to Biden, and Kate Bedingfield, Biden's communications director. It was sent after Giuliani appeared on three Sunday morning shows: ABC's "This Week," CBS' "Face the Nation," and Fox News' "Sunday Morning Futures."

In response, Giuliani told the Daily Beast that Biden's campaign is engaging in "left wing censorship."

"Everything I say is supported by such as today, affidavits and statements. They are the ones who have covered up pay for play for at least 5 years," Giuliani said.
