The Secret Service is investigating an adviser to Donald Trump after he said that Hillary Clinton should be killed for committing “treason”.

Al Baldasaro said during an interview with a Boston radio show that Ms Clinton should be “put in the firing line” over the misuse of her personal email server during her tenure as secretary of state.

“She is a disgrace for any, the lies she told those mothers about their children that got killed over there in Benghazi,” he said on the Jeff Kuhner Show.

“She dropped the ball on over 400 emails requesting back up security. Something's wrong there.”

“Hillary Clinton should be put in the firing line and shot for treason,” he added.

In response, Secret Service spokesman Robert Hoback told The Daily Beast that they are “aware” of the matter and “will conduct the appropriate investigation”.

Mr Baldasaro told The Independent: "They can investigate all they want. I've got nothing to say."

The state representative is attending the Republican National Convention this week where Mr Trump has officially been declared the party nominee.

He stood behind Mr Trump’s former campaign manager as Corey Lewandowski read out the roll call for the state of New Hampshire, grinning and wearing a baseball hat bearing the slogan “Make America Great Again”.

He recently stood alongside Mr Trump at Trump Tower on Fifth Avenue, angrily condemning the press for writing that Mr Trump took six months to reveal which military veteran charities he had donated millions of dollars to.

“You need to get your head out of your butt,” the New Hampshire state representative shouted.

Ms Clinton was cleared of any criminal wrongdoing this month by the Department of Justice and the Federal Bureau of Investigation despite sending and receiving top secret and classified information from an unsecured email account, which might well have resulted in “hostile adversaries” gaining access to that information, said by FBI director James Comey.

Mr Comey argued, however, that no “reasonable prosecutor” would pursue criminal charges against the democrat as she did not intend to break the law and he found “no evidence” that she attempted to hide information from the FBI.
