Senator Mike Lee of Utah drew criticism for posting messages on social media blaming the Minnesota lawmaker's assassination on 'Marxists' and mocking the state's Democratic governor, though he later issued a more serious condemnation of the violence.
Former President Donald Trump has proposed using Section 212 (f) of the Immigration and Nationality Act to deny entry to all "communists" and "Marxists" into the United States. However, existing U.S. immigration law already bars members of Communist Parties from becoming naturalized citizens or green card holders, with some exceptions. Trump's proposal raises questions about the legality and implementation of such a ban, as well as its focus on political theories that have limited support in the country. Critics have drawn parallels to Trump's controversial travel ban on Muslims, which was upheld by the Supreme Court. If implemented, the ban would primarily affect China, where millions of people are members of the Communist Party. However, the number of communists and Marxists in the U.S. is relatively small, and the rhetoric serves as a way for Trump to appeal to his base and target voters' emotions.
