Behind closed doors, frustrated Trump has been mocking the physical disability of Senator John McCain, who helped kill GOP’s Obamacare repeal and is currently fighting brain cancer.

The Senator’s daughter, Meghan McCain, is furious by the news and voiced her displeasure with Trump’s cruelty on Twitter.

Senator McCain cast the 51st and deciding vote against the Senate’s original Trumpcare bill this summer with a dramatic and unexpected thumb-down toward Senate Republican Leader Mitch McConnell.

Axios reports that the president has been mocking the gesture from Senator McCain who has limited use of his arms due to his years locked in a Vietnamese torture cell. Additionally, during the campaign, Trump make fun of McCain’s time as a prisoner of war, saying “I like people who weren’t captured.”

Verified Politics reports: “Certainly, we can and should have political disagreements with McCain, but respect for his service should be a given.

It takes a special kind of hypocrisy to simultaneously denigrate black athletes for kneeling during the National Anthem and ridicule the disabilities that a war hero incurred in his service to our country.

Once again, Trump’s actions are truly shameful. Today, Meghan McCain speaks for all of us.”
