Michael Donahue has dropped his Republican primary challenge to Brendan Doherty in Rhode Island's 1st Congressional District.
Donahue said on WHJJ radio Monday that he prefers to focus on his run for the General Assembly from the 68th District, which includes parts of Bristol and Warren.
Doherty seeks the seat now held by Democratic Rep. David N. Cicilline.
