Texas Sen. Ted Cruz abruptly ended his presidential campaign Tuesday night after falling to Donald Trump in Indiana's primary, a devastating loss that left him with no viable path to the Republican nomination. Trump, considered a fringe candidate a year ago, now is poised to represent Republicans in the fall presidential campaign.

"I've said I would continue on as long as there was a viable path to victory; tonight I'm sorry to say it appears that path has been foreclosed," Cruz told a somber crowd in Indianapolis.

Cruz campaigned aggressively in Indiana, but could not overcome Trump. The billionaire businessman has stunned the Republican Party with his appeal to voters deeply frustrated with Washington and their own party's leaders.
