SAN DIEGO (AP) -- Donald Trump hitting back at Hillary Clinton via Twitter after a speech that eviscerated his plans for America's foreign policy.
The presumptive Republican nominee says this of his likely Democratic rival: "Bad performance by Crooked Hillary Clinton!"
He adds: "Reading poorly from the teleprompter! She doesn't even look presidential!"
Clinton argued in her speech Thursday that Trump lacks the temperament and experience to be president. She says electing the billionaire businessman would be a "historic mistake" for the United States.
But Trump says the former secretary of state and likely Democratic nominee "no longer has credibility" due to "too much failure in office."
He says, "People will not allow another four years of incompetence!"
Hillary Clinton says electing Donald Trump president would be a "historic mistake" for the United States.
The likely Democratic nominee for president is casting Trump as thin-skinned, irrational and unprepared to be commander in chief.
She says his vision for America is "all wrong." She is urging voters to remember that the U.S. is a "big-hearted, fair-minded country."
Clinton's comments came in a foreign policy speech that held her most blistering criticism to date of the presumptive Republican nominee for president.
The remarks signal that Clinton won't hold back in challenging the billionaire businessman's readiness to be president in the general election.
