Hillary Should be Put in the Firing line and Shot: Trump's Campaign Adviser

The US Secret Service has launched an investigation on an informal adviser to Republican Presidential nominee Donald Trump after he called for Democratic Presidential nominee Hillary Clinton's execution.

Al Baldasaro, a New Hampshire state representative, on Tuesday, told radio host Jeff Kuhner that Clinton "should be put in the firing line and shot for treason."

Baldasaro, who serves as an informal adviser to Trump on veterans issues, has been one of Trump's most prominent supporters n the campaign trail, frequently introducing the candidate at events in New Hampshire.

The U.S. Secret Service is aware of this matter and will conduct the appropriate investigation," said Shawn L. Holtzclaw, a spokesman for the Secret Service.

Trump spokeswoman Hope Hicks told CNN, "The campaign does not agree with those statements."

She declined to characterize Baldasaro's role with the campaign or whether he would continue to travel with Trump on any future occasion.

"Donald Trump's overtaking of the Republican Party and his constant escalation of outrageous rhetoric is in danger of mainstreaming the kind of hatred that has long been relegated to the fringes of American politics where it belongs," Jennifer Palmieri said.

Arkansas Senator, Tom Cotton, while talking to CNN on Wednesday objected to Baldasaro's comments.

"That's not keeping with the best traditions of American politics. We have opponents. We have adversaries. We don't have enemies in American politics so I can't agree with that kind of rhetoric," Cotton, a former U.S. army infantry officer, told CNN.
