Nikki Haley has won the Republican primary in the District of Columbia, marking her first victory of the 2024 campaign.

Her victory on Sunday at least temporarily halts Donald Trump’s sweep of the Republican voting contests, although the former president is bound to pick up several hundred more delegates in this week’s Super Tuesday races.
