This link will take you to the text of the president's speech, fact checked and annotated by reporters from National Public Radio. Lots of others are fact checking, too. In general (no surprise) the speech is not getting very good grades for veracity.
The president's speech was presented to a hugely enthusiastic audience gathered on the South Lawn of the White House (and let's be clear, the crowd was definitely not observing health advisories that tell us that large assemblies are contraindicated during our current coronavirus pandemic).
Afterwards, the president's speech was followed by one of the most impressive fireworks displays I have ever seen, centered on the Washington Monument, and clearly visible from the South Lawn. As the fireworks came to a close, they spelled out "TRUMP," making the implicit claim that our nation's capital, and all of its official buildings and monuments, are all now subsidiary to the TRUMP brand. The Hatch Act be damned, Donald J. Trump "owns" our government. That really is the claim.
Carl Sandburg is quoted as follows:
If the facts are against you, argue the law. If the law is against you, argue the facts. If the law and the facts are against you, pound the table and yell like hell.
