The Chairman of the Republican National Committee has acknowledged the likelihood that Donald Trump will be the presumptive nominee of the party, following the suspension of the Ted Cruz campaign.

GOP Chairman Reince Priebus tweeted the a statement, shortly after Texas Senator Ted Cruz announced he was bringing his campaign.

Cruz had been labeling himself as the only alternative to a Trump nomination, despite the mathematical challenges ahead of him.

Following a poor showing in Indiana, Cruz ended his campaign. Priebus posted to Twitter calling Trump the presumptive nominee.

"We all need to unite and focus on defeating Hillary Clinton," Priebus wrote.
