Hillary Clinton accused Donald Trump of insulting America’s veterans and pressing dangerous military plans around the globe on Tuesday, seeking to undercut his appeal to service families in Southern voting battlegrounds. Trump declared “our country is going to hell” because of policies she would make even worse.

Clinton, addressing supporters in Florida, warned that Trump would lead the nation back to war in the Middle East. And to military vets and their families, she pointed anew to his summertime dust-up with the Muslim parents of a slain American soldier.

“His whole campaign has been one long insult to all those who have worn the uniform,” the Democratic nominee said at the University of South Florida in Tampa.

Republican Trump, trying emphasize his military support, released a letter from 88 retired generals and admirals citing an urgent need for a “course correction” in America’s national security policy. It was aimed at rebutting Clinton’s arguments that she would be best positioned to lead the military and reassuring Republicans who have openly worried that his provocative statements might undermine U.S. alliances.

“We believe that such a change can only be made by someone who has not been deeply involved with, and substantially responsible for, the hollowing out of our military and the burgeoning threats facing our country around the world,” the military leaders wrote. “For this reason, we support Donald Trump’s candidacy to be our next commander in chief.”

Clinton pushed back, saying Trump has lagged in securing key military supporters compared to past Republican nominees including John McCain and Mitt Romney. She pointed to her endorsements from retired Marine Gen. John Allen, who blasted Trump at the Democratic National Committee, and former CIA deputy director Mike Morell.

“They know they can count on me to be the kind of commander in chief who will protect our country and our troops, and they know they cannot count on Donald Trump,” Clinton said en route to Florida. “They view him as a danger and a risk.”

The conflicting messages came as the candidates prepared to appear at an MSNBC forum Wednesday night on national security. While they will appear separately and not be on stage at the same time, it could serve as a warm-up to their highly-anticipated first presidential debate on Sep. 26 in New York.

Campaigning in Virginia Beach, Virginia, Trump vowed to take aggressive action to help veterans at home and confront threats abroad including acts of terrorism from the Islamic State group. He was questioned by retired Gen. Michael Flynn, the former director of the Defense Intelligence Agency who is a strong supporter.

“We are going to solve the ISIS problem,” Trump said. “But we have to get back to building our country, because our country is going to hell.”

Trump promised to fix problems at the Veterans Administration, which has grappled with patient care mismanagement during the Obama administration. Until those problems are resolved, he said he would allow veterans to seek treatment at private doctors or hospitals free of charge.

“Your government is going to pay your bill,” he pledged.

Clinton’s message was amplified by her running mate, Virginia Sen. Tim Kaine, who was telling a North Carolina audience that Trump has misled voters on his views on the Iraq war and intervention in Libya.

Excerpts of Kaine’s speech, which was billed by Clinton’s campaign as a major national security address, painted Trump as dishonest, clueless and dangerous when it comes to national security.

Kaine was saying Trump tells voters he was opposed to the Iraq War even though he expressed support for it leading up to the U.S. invasion.

Meanwhile, Clinton’s campaign released a new television ad entitled, “Sacrifice,” that shows military veterans watching some of the New York businessman’s more provocative statements.

The spot includes clips of Trump claiming to know more about the Islamic State group than military generals, and his criticism of McCain, the Republican senator from Arizona and a former prisoner of war. The ad, which features former Georgia Sen. Max Cleland, a triple-amputee who served in Vietnam, also keys on Trump’s assertion that he has sacrificed a lot compared to families who have lost loved ones in conflict.

“Our veterans deserve better,” reads a line at the end of the ad, which is airing in Ohio, Florida, Iowa, Nevada and Pennsylvania.

Republicans, too, have questioned Trump’s capacity to serve as commander in chief. Dozens of GOP national security leaders released a letter last month warning that he would risk the nation’s “national security and well-being.”

Separately, Trump continued to face questions about his immigration policy a day after refusing to rule out a pathway to legal status for immigrants in the country illegally. He focused on his proposed border wall plan in a Tuesday interview with ABC’s “Good Morning America.”

Last week in Phoenix, he told a raucous crowd of supporters that there was “one way only” for immigrants here illegally to become legal — to return home and get in line for official readmittance.
