“Many members are supporting Trump quietly,” Rep. Chris Collins (R-N.Y.) told New York radio host Bob Lonsberry on Wednesday in an interview, according to a report by BuzzFeed News.

“They don’t like Ted Cruz at all, and for various reasons unique to their particular congressional districts they’re not formally endorsing Mr. Trump.”

Collins endorsed Trump in February, becoming one of the first lawmakers to do so.

He said Wednesday he hasn’t received “negative feedback” from other Republicans for the endorsement, which he made after Trump’s victory in the Nevada caucuses.
