What did Donald Trump do today?

He tried to take credit for something President Obama did, for the second day in a row.

Trump has held his last two press appearances at his luxury golf resort in Bedminster, New Jersey, with club members in attendance as well as reporters. The idea seems to be that Trump supporters will clap for him on cue—which they have.

That came in handy for Trump today as he claimed, for the second straight day, to have done something that was actually done President Obama. Yesterday, it was guaranteeing health insurance for people with pre-existing conditions. Today, it was the Veterans' Choice program, which allows servicemembers to seek medical care outside the VA system. It was signed into law in 2014.

TRUMP: We passed Choice, as you know, Veterans' Choice and Veterans' Accountability, and they've been trying to get that passed for decades and decades and decades, and no president's ever been able to do it, and we got it done.

Again, a president was "able to do it" in 2014. Trump signed a technical update in 2018, a totally uncontroversial bill that passed Congress with huge majorities.

Trump has told this lie more than 150 times. 

When reporter Paula Reid of CBS news pointed out that Trump's claim to have signed a bill that became law three years before he took office was false, Trump abruptly ended the press conference and fled the podium without answering.

Why does this matter?

• It's wrong to take credit for things other people have done.

• Telling a lie over and over again doesn't make it true.

• Running away from simple questions isn't a great look for a president.
