So much for presidential promises.

Donald Trump reportedly had pledged to Meghan McCain, daughter of Sen. John McCain, that he no longer would criticize his fellow Republican.

McCain is fighting a virulent form of brain cancer. His daughter revealed only recently about a conversation she had with the president about his vow to be kinder to the stricken senator.

Then the president stood before the Conservative Political Action Conference and tore into — that is correct — Sen. John McCain over his “no” vote on plans to repeal the Affordable Care Act.

Trump said this today to the CPAC audience: “Remember — one person walked into a room when he was supposed to go this way,” Trump added, giving a thumbs up sign, “and he walked in and went this way [thumbs down] and everyone said, ‘What happened? What was that all about? Who was that?’ I don’t know, I don’t know, I don’t want to be controversial so I won’t use his name. What a mess.”

If you can get past the mangled syntax and the idiotic sentence structure of the president’s remarks, then you’ll understand that the president is doing precisely what he told the senator’s daughter he wouldn’t do.

In Trump World, a promise made is a promise to be broken.

Liar.
