A freshman Republican from Texas took a step not many other GOP lawmakers in his state’s delegation have taken: calling out President Donald Trump by name for his ongoing, post-mortem feud with the late Sen. John McCain.

“I disagree with the POTUS standing in front of M1A1 Abram tanks & the American flag and spending time trashing POW veteran and former US Senator McCain,” Rep. Chip Roy tweeted late Wednesday.

The freshman Republican, Sen. Ted Cruz‘s former chief of staff, also criticized Trump for labeling the U.S. military and diplomatic campaign in the Middle East an “unqualified disaster” in the president’s winding, off-script speech in Lima, Peru, on Wednesday.

“I agree we should be re-think our strategy & engagement [in the Middle East], but words matter to the heroes who have bled the ground red and accomplished much in the process,” Roy tweeted.
