What did Donald Trump do today?

He did some campaign fund-raising.

Several hours before Trump gave a nationally televised prime-time Oval Office speech, his 2020 presidential campaign sent out a fundraising e-mail referencing the speech. He invited people to have their names put on "a list of EVERY AMERICAN PATRIOT who donates to the Official Secure the Border Fund," and said that the list would be delivered to him after the speech.

The "Official Secure the Border Fund" is a Trump campaign account. 

Previous prime-time presidential addresses have dealt with matters like the killing of Osama bin Laden, the September 11th attacks, other major military and diplomatic actions, national tragedies, and scandals affecting the president personally. 

No president prior to Trump is known to have tried to use a presidential address as a fundraising tool.

Why does this matter?

• The point of governing is to govern, not to fund the next campaign.
