Trump administration officials are suggesting their immigration crackdown could expand to include deporting convicted U.S. citizens and charging anyone — not just immigrants — who criticizes Trump’s policies. Here are 3 tactics the administration has teased that legal analysts say would challenge Americans’ rights:

1. Sending convicted U.S. citizens to prisons abroad.

2. Putting critics of the administration’s policies in jeopardy.

3. Questioning the authority of court orders.
