Texas Sen. Ted Cruz will end his presidential campaign on Tuesday after failing to top Donald Trump in the Indiana Republican primary, a high level campaign source tells NBC News.
NBC News projects Cruz will finish second, well behind Trump in a state that was crucial for Cruz to win in order to prevent Trump from gaining the 1,237 delegates needed to secure the presidential nomination.
Over the past week, Cruz said he would remain in the race as long as a "viable path" to the nomination exists. But Trump's commanding victory is projected to deliver him well over 40 delegates, making it unlikely the frontrunner fails in getting a majority of the delegates.
