Former president Donald Trump continued his march toward the Republican nomination as he won caucuses in Idaho and Missouri on Saturday and swept the delegate haul at a party convention in Michigan.
Mr Trump earned every delegate at stake on Saturday, bringing his count to 244 compared to 24 for former UN ambassador Nikki Haley.
A candidate needs to secure 1,215 delegates to clinch the Republican nomination.
The steep odds facing Mrs Haley were on display in Columbia, Missouri, where Republicans gathered at a church to caucus.
Seth Christensen stood on stage and called on them to vote for Haley. He was not well received.
Another person shouted out from the audience: “Are you a Republican?”
An organiser quieted the crowd and Mr Christensen finished his speech.
Mrs Haley went on to win just 37 of the 263 Republicans in attendance in Boone County.
