Shortly after Donald Trump’s victory in Indiana last night, John Kasich had vowed to continue on until a candidate earns the needed 1,237 delegates to become the nominee. Well, in the span of less than 12 hours, that decision seems to have crumbled as Kasich will make an announcement today at 5pm ET from his home state of Ohio.

Report from Fortune:

Ohio Gov. John Kasich will announce the suspension of his campaign for President of the United States, senior advisers told NBC News Wednesday.

Kasich has cancelled a press conference in Virginia and plans to make a statement from Columbus, a day after one of his last remaining rivals, Ted Cruz, ended his campaign. Kasich has faced increasing pressure to drop out of the race to clear the path for front-runner Donald Trump to win the nomination.

Kasich had planned fundraisers in the Washington, D.C., area Wednesday. He had planned to address reporters at Dulles Airport but his campaign says he is no longer going there.

With Ted Cruz out as of yesterday, and John Kasich suspending today, that leaves only Donald Trump as the presumptive GOP nominee. At this point, it’s basically a done deal as the party will now move forward and attempt to unify after a bitter primary battle.

GOP Chairman Reince Preibus may have helped make Kasich’s decision for him with this tweet from last night:
