Ted Cruz urges rivals to drop out of the race to leave it a straight fight between him and Trump for Republican nomination
Ted Cruz called for some of his Republican rivals to drop out of the race for the White House after he won Oklahoma and his home state of Texas.
Though he did not mention Marco Rubio or John Kasich by name, he made it clear that he felt they should quit so Republicans could consolidate around him as a viable alternative to Donald Trump.
He asked them "prayerfully consider" the future of their campaigns, warning that as long as the Republican field remained divided, Mr Trump would have a path to nomination, which he declared "a total disaster" for his party.
Former candidate Lindsey Graham said the only way to stop Mr Trump from becoming the party's nominee and winning the general election may be to rally behind Mr Cruz.
The South Carolina senator said: "Ted Cruz is not my favourite by any means. But we may be in a position where rallying around Ted Cruz is the only way to stop Donald Trump and I'm not so sure that would work."
He called both Mr Trump and Democratic front-runner Hillary Clinton "crazy" and said the Republican party is bound to lose to Mrs Clinton if an alternative to Mr Trump is not found.
Retired neurosurgeon Ben Carson told a crowded banquet hall at a hotel in Baltimore that he is not giving up, despite trailing behind all the other Republican candidates on Super Tuesday.
He took to the stage at the Grand Hotel and called the political system "rotten to the core".
Mr Carson said: "They have weaved such a complex web."
He did not mention any of his opponents by name, but told his supporters: "Our nation is in horrible trouble. Why sit there and talk about each other and tear each other down when we have such important issues to deal with?"
