A senior Twitter manager who has called for jailing and impeaching President Trump and slammed the White House social media chief with four-letter slurs is raising concerns that the platform isn’t serious about policing hate posts.

Twitter Senior Engineering Manager Ian Brown’s tweets have assailed Trump, White House social media chief Dan Scavino Jr., top aide Stephen Miller, GOP lawmakers including Sen. Rand Paul, and supporters like Turning Point USA chief Charlie Kirk.

In a recent tweet he suggested that restaurant workers were tampering with Eric Trump’s food, after the president’s son said he was spit on at a Chicago eatery. “If @EricTrump is upset about getting spit on by a restaurant employee, I have some bad news about the food and drinks he’s being served,” Brown tweeted June 26.

I’m gonna go out on a limb here and guess that the answer is...wait for it...you are a racist dick. — Ian Brown (@igb) May 1, 2019

Brown’s tweets drew attention a year ago when he rapped Scavino's postings backing the president's immigration agenda, including criticism of "chain migration," right before Twitter shadow banned several conservative accounts.

Earlier this year Facebook blocked Scavino’s account, drawing fire from the White House. The administration has long felt that social media platforms promote anti-Trump hate while banning Trump supporters.

All I want for Christmas is for @DanScavino and @realDonaldTrump to go to jail next year. #MAGA — Ian Brown (@igb) December 25, 2018

“This is proof that these sites are not serious about policing the anti-Trump trolls,” said an administration adviser.

Brown referred a question about his tweets to Twitter’s communications office which offered no comment.

He is followed by Twitter CEO Jack Dorsey and top tech officer Parag Agrawal.

Can somebody impeach this motherfucker before it’s too late? https://t.co/jmP7pVW3al — Ian Brown (@igb) January 7, 2019

Associates said that the slams on Scavino, a long-time and close Trump aide who was a manager of a Trump golf course, were troubling because he heads the sprawling social media effort at the White House.

“The attacks on him are often and sometimes in disgusting ways,” said one.

Recently, Brown mocked the July 4th tweets by Scavino.

In an April post, he called Scavino “a racist dick.” In another, he wrote, “you are a racist hack and a hate-mongering jerk.”

.@DanScavino is too dumb to pass a CAPTCHA so I’m guessing all his racist "chain migration" garbage comes from his "buddy" Stephen Miller. https://t.co/uiCgDeTdOV — Ian Brown (@igb) April 7, 2019

He has also called for jailing Trump and Scavino and backed impeachment.

“Can somebody impeach this motherf----- before it’s too late,” he tweeted in January.

And on Christmas Eve, he wrote, “All I want for Christmas is for @DanScavino and @realDonaldTrump to go to jail next year. #MAGA.”

At a meeting in the White House last week that featured some social media bosses the president likes, Trump praised Scavino who turned from golf to social media during the 2016 campaign and took on Hillary Rodham Clinton’s big social media team.

He said: “There's nobody better at that and I think Hillary had 28 people and I had Dan. I had my Dan and he works at about 28 hours a day and he works very hard. He doesn't work. I mean he loves it. He loves it.”
