The Trump administration is considering issuing sweeping travel restrictions for the citizens of dozens of countries as part of a new ban, according to sources familiar with the matter and an internal memo seen by Reuters.

The Trump Administration is reportedly considering a new travel ban for citizens of up to 43 countries—a potential escalation of Trump’s first term travel ban which primarily targeted Muslim-majority countries.

A draft circulating inside the administration lists three tiers of countries whose citizens may face restrictions on entering the United States.

During President Trump’s first term, he created a series of bans against citizens from Muslim-majority countries.
