Donald Trump has been very successful in business and has helped people along the way, fellow GOP candidate Lindsey Graham conceded Thursday, but he still doesn't think he's ready to be the nation's commander-in-chief.
"Mr. Trump's policy solutions on immigration are unsound, they're unworkable," the South Carolina Republican senator told MSNBC's Andrea Mitchell on her noon program, "Andrea Mitchell Reports."
"His foreign policy views are dangerously naive."

"Deporting American citizens' children of illegal immigrants is unconstitutional," Graham continued. "On the foreign policy front, his approach to destroying ISIL by taking Iraqi and Syrian oil for our benefit would turn the whole Mideast against us and help ISIL."
But he said he still has faith that as summer comes to an end and the primaries draw more near, Americans will be ready to consider more serious issues.
Graham also told Mitchell that he hoped Trump would agree to sign an oath to promise to back the eventual GOP nominee, if he doesn't win the spot, and that the New York political newcomer won't mount a third-party bid if he loses the nomination.
"You know, the fact that we're having to sign an oath is not a good thing," Graham said. "If you're running as a Republican, it should be assumed, if you lose you're going to support the Republican nominee. If he signs the pledge that will be a great thing."
Trump did sign the pledge
On Thursday, Graham also disagreed with other party members when it comes to the case of Kentucky court clerk Kim Davis, who was jailed on contempt charges
Thursday after her continued refusal to offer licenses for same sex marriages.
"I sympathize with her religious beliefs but she's a public official and those of us in public life have to administer the law to every American as the law is written," said Graham.
