Roger Stone, a longtime ally of President Donald Trump, suggested Sen. Mark Kelly (D-Ariz.) should face “execution” after the lawmaker questioned Trump’s recent business ventures into cryptocurrency.

“Trump is cashing in on his presidency and making millions from his own crypto coins. It’s corruption in broad daylight,” Kelly wrote on X Wednesday, promoting the “End Crypto Corruption Act,” which he said would make it illegal for “the President, the Vice President, administration officials, and members of Congress to issue, sponsor, or endorse crypto assets for profit.”

Earlier this month, the State Democracy Defenders Fund pointed out that reporting suggested the president’s crypto offerings may account for nearly 40% of his wealth. The President has even invited people who invest in his $TRUMP meme coin to a private dinner at his golf club in Virginia.

“This bill puts forward a blanket prohibition on acts that could be self-serving in order to guard against conflicts of interest,” Kelly wrote in Wednesday’s announcement.

In a responding post on X, Stone accused the lawmaker of “treason.”

“Senator Mark Kelly is cashing in on his US Senate seat as a partner in a Chinese communist company that makes surveillance balloons,” Stone wrote. “He should be charged with treason and if convicted executed , consistent with federal law.”

Kelly’s wife and mass shooting survivor Gabrielle Giffords responded to Stone’s comment on Friday, stating “Trump and his allies should understand that the threat of political violence is real.” Giffords was left in critical condition in 2011 after being shot in the head in an assassination attempt.

“It stole a job that I loved. Inciting violence is unAmerican — it’s what extremists do. Anyone serious about protecting this country should know the difference,” Giffords wrote.

Stone doubled down on his original statement in response to Giffords’ post.

“I said he should be TRIED and if convicted, of course the penalty for treason is capital punishment. But of course you left that part out. Typical left-wing distortion.!” Stone wrote.
