WASHINGTON ― One of Donald Trump’s advisers on veterans affairs wants Hillary Clinton to be shot for treason.

Al Baldasaro, a New Hampshire state representative and delegate for the Republican presidential nominee, made the comments during an interview on “The Kuhner Report” radio show on Tuesday.

Host Jeff Kuhner asked if Baldasaro thought Clinton bore responsibility for those who died in the 2012 terrorist attack on a U.S. compound in Benghazi, Libya.

“I’m a veteran who went to Desert Shield, Desert Storm. I’m also a father who sent a son to war, to Iraq, as a Marine Corps helicopter avionics technician. Hillary Clinton, to me, is the Jane Fonda of the Vietnam,” Baldasaro replied, referring to Fonda’s 1972 trip to Hanoi that some Americans consider to be an act of betrayal.

“[Clinton] is a disgrace for the lies that she told those mothers about their children that got killed over there in Benghazi. She dropped the ball on over 400 emails requesting back up security. Something’s wrong there,” he continued.

“This whole thing disgusts me,” Baldasaro added. “Hillary Clinton should be put in the firing line and shot for treason.”

After an extensive investigation into Clinton’s private email server, the FBI and Justice Department decided no charges were appropriate. And after spending more than two years and $7 million, the House Select Committee on Benghazi found no evidence of wrongdoing by the then-secretary of state.

BuzzFeed News first reported Baldasaro’s comments. On Wednesday, he stood by them, telling ABC affiliate WMUR that “As far as I’m concerned, it is treason and the penalty for treason is the firing squad ― or maybe it’s the electric chair now.”

The U.S. Secret Service said it is aware of Baldasaro’s comments and will conduct “the appropriate investigation,” Politico reported.

The Trump and Clinton campaigns did not immediately respond to requests for comment from The Huffington Post.

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims ― 1.6 billion members of an entire religion ― from entering the U.S.
