The following Tweet was censored by Twitter:

“CBP & U.S. Army Corps of Engineers continue to build new wall every day.

“Every mile helps us stop gang members, murderers, sexual predators, and drugs from entering our country.

“It’s a fact, walls work.”

The reason for the censorship?

“You may not promote violence against, threaten, or harass other people on the basis of race, ethnicity, national origin, sexual orientation, gender, gender identity, religious affiliation, age, disability, or serious disease.”

Mark Morgan, the Senior Official Performing the Duties of Commissioner of U.S. Customs and Border Protection (CBP) had his account locked.

Acting Homeland Security Department Secretary wrote Twitter CEO Jack Dorsey the following:

“It is hard to understand how anyone believed Mr. Morgan’s tweet promoted violence, threats or harassment.

“Especially considering that the facts about the border wall system support the tweet.”
