Former Florida Gov. Jeb Bush on Wednesday called GOP presidential front-runner Donald TrumpDonald TrumpTrump defends indicted GOP congressman House to vote Thursday on holding Bannon in contempt Youngkin calls for investigation into Loudoun County School Board amid sexual assault allegations MORE a national security threat for his call to halt Muslim immigration — a plan Bush panned as "ridiculous."
"It’s not a proposal, it’s a sentiment, it’s a way to fulfill people's deep anxiety and fear," he said on Fox News's "The Kelly File."
"Trump is a master at this, but the simple fact is: He doesn't have a plan, he's not serious and he's jeopardizing our ability to create a strategy to take out ISIS."
Bush added that Trump's call sends "a chilling signal to our allies," particularly Muslim countries the U.S. is relying upon in the fight against the Islamic State in Iraq and Syria (ISIS). 
Bush and the vast majority of his GOP presidential rivals immediately rebuked Trump after he called for an immediate halt to all Muslim immigration into America on Monday. 
Bush took to Twitter to call Trump "unhinged" but refused to address whether he'd support Trump if he ends up the GOP’s nominee.
Ohio Gov. John Kasich is the only other candidate to publicly consider not backing Trump, though he has not committed.
Bush also accused the Obama administration of rolling back much of the safety measures put into place by his brother, President George W. Bush, after the Sept. 11, 2001, terrorist attacks.
"It's the tactics of intelligence-gathering that has been restricted," he said, lamenting the limitations on the National Security Agency’s surveillance program and the fact that the administration is giving potential foreign terrorists civil liberties.
