After Hillary Clinton painted her Republican opponent as a man who “you can bait with a tweet” while accepting the Democratic nomination for president Thursday, Donald Trump took to his preferred medium to fire off a few shots.

Trump claimed on Twitter that Clinton devoted insufficient attention to the threat posed by “Radical Islam” and that she advocated a “borderless world.”

Though Trump’s attacks focused primarily on national security, which was the focus of his own speech at the RNC last week, he painted with a broad brush, knocking Clinton’s donations from Wall Street and alleging that “corruption and devastation follows her wherever she goes.”

Clinton said in her own remarks that Trump’s no-holds-barred style was proof that he lacked the “temperament to be commander-in-chief.”

“He loses his cool at the slightest provocation,” she said. “When he’s gotten a tough question from a reporter, when he’s challenged in a debate. When he sees as protester at a rally. Imagine, if you dare imagine, imagine him in the Oval Office facing a real crisis. A man you can bait with a tweet is not a man we can trust with nuclear weapon.”

Trump countered that Clinton had the “worst judgement [sic].”

Trump Senior Policy Advisor Stephen Miller backed up his boss’ accusations in a statement, labeling Clinton a “globalist” who described a “fantasy universe” in her speech. He also chastised her for not mentioning the 2012 terrorist attacks in Benghazi, Libya, in her speech. An entire evening was devoted to them at the RNC.

No one has worse judgement than Hillary Clinton – corruption and devastation follows her wherever she goes. — Donald J. Trump (@realDonaldTrump) July 29, 2016

“Hillary Clinton’s speech was an insulting collection of clichés and recycled rhetoric. She spent the evening talking down to the American people she’s looked down on her whole life.

Hillary Clinton talks about unity, about E Pluribus Unum, but her globalist agenda denies American citizens the protections to which they are all entitled – tearing us apart. Her radical amnesty plan will take jobs, resources and benefits from the most vulnerable citizens of the United States and give them to the citizens of other countries. Her refusal to even say the words ‘Radical Islam’, or to mention her disaster in Libya, or her corrupt email scheme, all show how little she cares about the safety of the American people.

It’s a speech delivered from a fantasy universe, not the reality we live in today.
