The three GOP candidates for U.S. Senate will face off for the first time Tuesday in Easton, according to the Boston Globe.

State Rep. Dan Winslow (R-Norfolk), former U.S. Attorney Michael Sullivan and former Navy SEAL Gabriel Gomez will participate in an hour-long forum starting at 7 p.m. at Stonehill College. The debate will be live-streamed on WCVB-TV’s website.

The three candidates are vying for the Republican nomination in the April 30 primary. The winner will take on the winner of the Stephen Lynch-Edward Markey battle on the Democratic side of the ballot.
