President Trump's 2020 campaign manager Brad Parscale and the Republican National Committee are taking their fight against the censorship of conservative views right to the source.

Parscale and the RNC on Thursday sent a letter to Facebook and Twitter expressing concern about conservative voices being suppressed and asking the social media giants for transparency about how they will ensure that everyone has a voice on their platforms.

"I think the public deserves that transparency, and we need to know that conservative voices have a chance to get their messages out," Parscale said on "Fox & Friends."

RNC Chair Ronna McDaniel noted popular conservative vloggers Diamond and Silk were temporarily blocked on Facebook, and they've also heard from conservative candidates who have been shut down after launching on the social media platforms.

She said it's important to make sure there's not a "thought police" coming from Silicon Valley.

"They live in a liberal bubble in Northern California," Parscale agreed, calling for transparency in social media companies' algorithms and explanations for why people are banned.

"We saw this during the 2016 campaign, where they were manually manipulating trends, we've seen this with the algorithm changes, we've seen reductions in Trump's reach on the platform. And I want to make sure they're done evenly."
