Sen. Patrick Leahy, D-Vermont, on Thursday introduced legislation to limit the Department of Homeland Security's ability to stop vehicles and search private land.

Currently, DHS can conduct stops looking for illegal aliens within 100 miles of the border, a distance the senator calls "unreasonably wide."

Under new directives from the Trump administration, Customs and Border Protection agents in Vermont recently have boarded Greyhound buses without a warrant. In Maine and New Hampshire, immigration checkpoints have been set up on interstate highways.

The new legislation would reduce the "border zone" from 100 miles down to 25 miles and would reduce the zone in which DHS officers may enter onto private property from 25 miles down to 10 miles.

The bill will be referred to the Senate Judiciary Committee.
