“It might be Canada,” Trump quipped, mocking Cruz’s birthplace.

“He didn’t even know what state he comes from. Fort Hood is from Texas by the way. I am so surprised, Anderson, that you let him get away with it.”

Cruz accidentally called Florida as his home state while discussing a 2009 mass shooting at Fort Hood, Texas.

“My home state of Florida — Fort Hood,” Cruz said when discussing the military base located in Killeen, Texas.

Cruz was discussing radical Islamic terrorism, citing the attack by a Muslim U.S. Army major and psychiatrist nearly seven years ago.

Nidal Hasan was convicted of killing 13 people and wounding 32 others after he admitted he had opened fire at the military installation.

“I am the shooter,” he said during his court-martial in August 2013.
