The dinner included the Facebook board member Peter Thiel - the investor and entrepreneur who cofounded PayPal and Palantir and who supports Trump.
Ahead of the 2020 US Presidential election and just weeks away from the UK General Election, Facebook founder and CEO Mark Zuckerberg has dug in on his decision to allow the spread of false information on the social media platform.
The meeting was not previously disclosed and only surfaced later in news reports. He denied that Trump lobbied him.
While he was in town, Zuckerberg met with President Donald Trump for a private dinner that also included the Facebook board member Peter Thiel.
Mark Zuckerberg is many things, but an eloquent and reasoned defender of secret meetings with the world's most powerful is not one of them.
Facebook is facing a backlash because it did not become a member of Twitter, which stopped accepting political ads last month. Segments of the interview, more of which will be broadcast on December 3, are peppered with what we have come to know as classic Zuckerberg moments. "I also want to respect that it was a private dinner and...private discussion", he said.
"I mean, I don't think that that's - that - I think some of the stuff that people talk about or think gets discussed and these discussions are not really how that works", Zuckerberg mentioned.
When asked if that is possible with patently false claims, Zuckerberg said "people should be able to judge for themselves the character of politicians".
According to the ad library Facebook, the Conservative Party spent less than £ 10,000 ($ 12,930) in the ad, which was viewed about 430,000 times.
In the interview, Zuckerberg echoed previous statements he'd made about the choice.
During a lengthy CBS interview, Zuckerberg dismissed the idea of changing the controversial policy, claiming in a democracy "it's really important people can see for themselves what politicians are saying, so they can make their own judgments".
The most awkward man in tech for some reason recently chose to sit for an interview with CBS's morning news co-host Gayle King to discuss, along with his wife Priscilla Chan, the duo's Chan-Zuckerberg Initiative.
