George Patton “Pat” Waters, grandson of the iconic World War II commander Gen. George S. Patton, endorsed Sen. Marco RubioMarco RubioAt CPAC, Trump lashes out at media Conquering Trump returns to conservative summit Rubio brushes off demonstrator asking about town halls MORE (R-Fla.) for president on Wednesday.
"Marco Rubio is tough, honorable, and experienced. His judgement is sound and his plans to keep America safe will work," Waters said in a statement Wednesday.
"Donald Trump says we need to bring back Patton, but I can say with certainty: Mr. Trump, you are no Patton," Waters said.
"It's true that my grandfather was known for his controversial statements and aggressive leadership, but he was also known for his honor and toil for a righteous cause. He put his men and mission above himself every time," he added.
Trump has prompted criticism from retired military commanders who say it would be illegal for troops to carry out his calls for torture of terrorist suspects and the killing of their families.
"Donald Trump is driven only by his own self-interest. He has no north star on matters of foreign policy," Waters said. "He is neutral when it comes to Israel, America's greatest ally, and friendly toward Vladimir Putin."
Waters commended Rubio's campaign against Trump, who has hit the Florida senator for being a "lightweight."
"My grandfather was a fighter, and he would have been proud of Marco Rubio’s fight against Donald Trump," Waters said.
"When Marco gets hit, he hits back. My grandfather once said, 'We got through on good old American guts.' That will be the story of Marco Rubio after he wins here in Florida. I am proud to support him as he makes a stand for America's future," he said.
Rubio faces a tough fight in his home state after a disappointing night on Tuesday, when he only garnered 5 percent of the vote in the Mississippi primary, 9 percent in Michigan and 16 percent in Idaho. Florida's winner-take-all primary will be held on March 15.
