Good morning. I'm Kate Baldwin. It is Friday, May 1st. Here are the five things you need to know to start your day.

Number one, the surveillance video. There is still more new video coming out of the lead-up to the attempted attack on the White House Correspondence dinner.

Federal prosecutors say this video shows Cole Thomas Allen

casing the hotel the night before the attack. They say the video shows him walking through

corridors, even checking out the hotel gym Friday night, and the hall also that would lead

to the dinner's security checkpoint. Then the video cuts to the scene that very next night when Alan storms through that checkpoint.

The US Attorney for DC says this video shows Alan shoot a secret service officer, though it is not clear when that moment occurs.

Still, Janine Piro says there is no evidence that the officer that was shot was hit by friendly fire. What we do know is that he fired off that 12-gauge shotgun one time. The cartridge was

still in the weapon. He fired that gun in the direction of the Secret Service officer.

And what we do know is that the Secret Service officer fired his weapon five times.

The Secret Service agent did not shoot himself.

Then there's also the selfie that prosecutors revealed.

Alan in his hotel room with several weapons on him.

They were planning the prosecutors to release all of this in court

yesterday to argue Alan needs to stay in custody as he awaits trial, but then Alan

agreed to remain in custody. So the judge said it would be a waste of time to

present the evidence, though prosecutors decided to release it anyway. Number two,

the Surgeon General. President Trump is testing the theory now that third times the charm when it comes to a surgeon general.

First, he nominated former Fox News medical contributor Dr. Jeanette Neshwatt, then Dr. Casey Means, a wellness influencer who faced up questions from lawmakers about her views on vaccines.

And the president now just pulled her nomination,

and he's nominated the third, Dr. Nicole Sapphire, a radiologist at Memorial Sloan Kettering Cancer

Center specializing in breast cancer. Sapphire has mixed views on vaccines. I guess you could describe it that way.
