Donald Trump has comfortably overtaken his rival Nikki Haley and won the Republican caucuses in Idaho, Michigan and Missouri.
The networks called Idaho for the former president just after 7 p.m. after 60 percent of the vote was counted, when he led Nikki Haley 85 points to 14.
The victory gives Trump an additional 32 delegates ahead of the Republican National Convention in July.
In Michigan, Trump defeated Haley in all 13 counties that went to nomination elections, securing 98 percent support overall, according to the Republican Party. It was the second part of the state nomination process.
The two contests complement an earlier victory in Missouri, where the race was called at 11:40 a.m., less than two hours after meetings began.
