According to a former US official, former Trump administration officials are not allowed to post on Twitter.
At least four Republican figures with experience in US foreign policy in the Middle East were unable to tweet late Monday.
Al Arabiya English could not independently verify the reason for the move.
The individuals include Marshall Billingslea, former Presidential Envoy under President Donald Trump and former Assistant Secretary of the Treasury for Terrorist Financing, Victoria Coates, Robert Greenway and Richard Goldberg.
Greenway was a former senior director at the National Security Council for the Middle East and North Africa under Trump. Goldberg and Coates were also senior officials in the Trump administration.
Twitter has not yet responded to a request for comment.
“On the night that [President] Biden is withdrawing our troops from Afghanistan, Twitter is shutting down high-ranking Republicans with experience in Afghanistan,” Billingslea told Al Arabiya English.
He and the other three individuals reported being unable to publish original tweets. Billingslea was able to “retweet” and send direct messages, but said he couldn’t see his own tweets.
