Representatives for Facebook, Twitter and YouTube testified before the House Judiciary Committee on Tuesday that there’s no political bias when blocking content from the sites, but not everyone is buying it.

Lawmakers grilled Facebook CEO Mark Zuckerberg in April over numerous reports the company runs interference between conservative groups and personalities and their followers, with several highlighting complaints from the Trump-supporting duo Diamond and Silk that Facebook deemed them “unsafe” and cut them off from their 1.4 million followers in a variety of ways.

Lynette “Diamond” Hardaway and Rochelle “Silk” Richardson also complained about YouTube demonetizing their popular videos.

Monika Bickert, Facebook’s head of global policy management, alleged at the Tuesday hearing the world’s largest social media company doesn’t censor political views, but acknowledged that Facebook bungled their response to the duo’s complaints about censorship, CNET reports.

“We badly mishandled our communications with them,” Bikert said, “and since then we’ve worked hard to improve our relationship. We appreciate the perspective that they add to our platform.”

“We don’t always get it right,” Juniper Downs, head of public policy for YouTube, told lawmakers.

Diamond and Silk appeared on Fox & Friends First early Tuesday to point out the online censorship of conservative views continues, despite claims to the contrary.

“We’re still being censored. People are not receiving our content. We’re not showing up in their news feed. They like our page, then they go back and the page is unliked. They can’t view our videos,” Hardaway said. “Sometimes when they come directly to our page, it won’t come up. And then even when they search us, we’re not even coming up in the search for some people.

“So yes, we’re still being censored by Facebook,” she said.

Facebook officials talk a good game, Richardson added, but they don’t walk the walk.

“And you have Mark Zuckerberg that have apologized to us, so he say, for an enforcement error, but have not corrected this so-called enforcement error,” she said. “You know, your actions speak louder than words. This let us know this is straight bias, and it’s intentional, and it is deliberate.”

Others at the Tuesday hearing pointed out how ridiculous social media censorship has become.

CNET reports:

Rep. Bob Goodlatte, the chairman of the Judiciary Committee and a Republican from Virginia, pointed to Facebook’s algorithm mistakenly blocking the Declaration of Independence on the Fourth of July.

“Think about that for a moment,” Goodlatte said in his opening remarks. “If Thomas Jefferson had written the Declaration of Independence on Facebook, that document would never have seen the light of day. No one would be able to see his words because an algorithm automatically flagged it.”

And while Democrats like Maryland Rep. Jamin Raskin framed the issue as “the totally imaginative narrative that social media companies are biased against conservatives,” several Republican lawmakers used specific examples to illustrate the problem.

“Much of the hearing fell along partisan lines, as many Republicans used their time to ask the Facebook, YouTube, and Twitter representatives questions about why content favorable to conservatives seemed to be censored or why pages or accounts encouraging violence against conservatives were not,” Venture Beat reports.

“Rep. Matt Gaetz (R-FL) questioned why a Facebook page that appeared to encourage violence against conservatives was still up on the platform, while Rep. Steve King (R-IA) asked why the Facebook traffic of far-right blog Gateway Pundit appeared to have dropped over the past year.”
