The Trump administration has covered a lot of ground when it comes to immigration, often battling federal courts over actions taken to crack down on undocumented immigrants, restrict travel to and from predominantly Muslim countries and fighting in Congress for funding for a U.S.-Mexico border wall.
A week into his presidency, Donald Trump announced a 90-day travel ban aimed at seven majority-Muslim countries — Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen — and a 120-day ban on refugees worldwide. That action was struck down by federal district and appeals courts. A second version of the ban was also struck down. In August, the Supreme Court upheld a third version of the ban that excluded Sudan and added Chad, North Korea and officials from Venezuela and made the ban indefinite instead of temporary.
