Donald Trump has won Missouri’s Republican caucuses, one of three events Saturday that will award delegates for the GOP presidential nomination.

The former president, who is especially strong in caucuses, was adding to his delegate lead in Republican caucuses in Missouri as well as at a party convention in Michigan. Idaho was scheduled to hold its caucuses later Saturday. Former U.N. Ambassador Nikki Haley, meanwhile, is still seeking her first win.

There are no Democratic contests Saturday.

In Missouri, the Republican Party held its presidential caucuses, offering state voters their only chance to weigh in on who should represent the party on the November presidential ballot.

Voters lined up outside a church in Columbia, home to the University of Missouri, before the doors opened.

“I don’t know what my role here will be, besides standing in a corner for Trump,” Columbia resident Carmen Christal said, adding that she’s “just looking forward to the experience of it.”
