That's exactly what happened with that proposal from two years ago. House Republican leaders withdrew a bill that would require biometric tests at border crossings in five to seven years amid pressure from Rep. Chris Collins, R-Clarence, and other lawmakers that represent border areas.

Collins did not respond to a request for comment for this story. But the congressman -- now a leading liaison between Trump and the House -- played a key role in killing the 2015 proposal, introducing an amendment that would have not allowed the biometric plan to go forward unless it was tested in a demonstration project first to determine if it would cause traffic chaos.

“What we want is just to make sure that anything we do, number one, works, and number two, doesn’t cause undue delays at our northern borders and for folks coming to Bills and Sabres games and going to the Galleria mall," Collins said at the time. "We can’t have backups at the Peace Bridge or Rainbow Bridge or any of the others that would dissuade Canadians from coming into this country and also inconvenience Americans.”
