A Georgia Republican whose comments criticizing President Donald Trump's remarks about John McCain were released earlier in the day has upped his condemnation of the president on Wednesday afternoon.

After noting that Trump will get a "whipping" over his McCain attacks and saying "the country deserves better" in comments shared exclusively with the conservative Bulwark website, Sen. Johnny Isakson (R-GA) was quoted saying what the president said was "deplorable."

"It’s deplorable what he said," Isakson remarked to a Georgia radio show. “It will be deplorable seven months from now if he says it again."

During a Tuesday press conference with Brazil's far-right president Jair Bolsonaro, Trump was asked about his criticisms of the late Arizona senator.

"I was never a fan of John McCain’s and I never will be," the president responded.
