Donald Trump Jr. posted an Instagram with a caption exceeding the word count of the Gettysburg Address hollering about what he perceives to be “censorship” of his account due to some amorphous “leftist activism.”

“This kind of leftist activism and censorship must finally stop. The attack on free speech cannot be allowed to continue on platforms as large as Instagram and with as much reach,” Trump Jr. wrote. “This is no longer a simple little error or coincidence as they keep claiming. This is a systematic and sustained one way attack.”

Trump Jr.’s diatribe was launched by a follower telling him that he or she could not like one of his posts.

Officials at Instagram did not immediately respond to a request for comment.
