 "Donald Trump")
Republican front-runner Donald Trump abandoned a pledge to support a party presidential nominee other than himself, a sign of increasing friction with chief rival Ted Cruz.
"No, I don't anymore," Trump replied, when asked at a CNN town hall event whether he still supported a pledge he made last year to support whoever is the Republican nominee for the November 8 election. Trump's signing of a loyalty pledge last September was important in helping him gain credibility within the Republican National Committee. The pledge was also signed by all his rivals for the presidential nomination.
His aboutface came as he tries to fend off a challenge from Cruz, a US senator from Texas, who is running second to the New York billionaire in the race for the 1,237 delegates needed to win the nomination.
