Vindman accuses Donald Trump Jr., Rudy Guiliani and others of conspiring to intimidate and then punish him for testifying in the former president's 2019 impeachment case.
President Trump denied culpability for the violence and expressed no regret for comments made last week that many have criticized as being a catalyst for mob violence at the U.S. Capitol.
The company said Trump Jr.'s account would be limited for 12 hours. It said the president's son put out a tweet with "misleading and potentially harmful" information about the coronavirus.
