BALTIMORE >> A federal judge in Maryland will rule later on three lawsuits requesting preliminary injunctions to block the most recent Trump administration travel restrictions.

A hearing was held today afternoon before U.S. District Judge Theodore D. Chuang.

The lawsuits argue that restricting travel for citizens of predominantly Muslim countries violates the U.S. Constitution.

The Trump administration in September announced the most recent restrictions, which affect citizens of Chad, Iran, Libya, North Korea, Somalia, Syria, and Yemen — and some Venezuelan government officials and their families. They’re to go into effect Wednesday.

In March, Chuang blocked a previous version of President Donald Trump’s revised travel ban targeting six predominantly Muslim countries. Chuang granted a preliminary injunction nationwide.
