WATCH: Complete bodycam footage of police discovering Trump shooter's body

Senator Chuck Grassley's office on Thursday released more bodycam footage from shortly after the attempted assassination of former US president Donald Trump on July 13.

The video shows officers from Beaver County Emergency Services and the Secret Service accessing the rooftop where shooter Thomas Matthew Crooks fired.

The officers gathered evidence immediately after the attack.

Grassley, a Republican from Iowa, is among many in Congress demanding a full investigation.

Secret Service Director Kimberly Cheatle resigned on Tuesday following harsh criticism for the agency's failure to prevent the attack.

The Secret Service now faces investigations from multiple congressional committees and the Department of Homeland Security's internal watchdog over its performance.

Warning: This video contains distressing content.

SS director said the angle of the roof was a danger to her people??? She should be in jail

So why is our news media not covering this? We get more info from Sky News Australia than we do here in the US.

[ItsMeJbird]

A blind man could see that they let this happen.

[johnkalin]

As a roofer I can confirm that roof is damn near flat

[joemontano]

4:44 The “sloped roof” excuse for not having agents posted up there was *ABSOLUTE BS.*

[mariadejesusr]

The general public spotted the shooter and they didn’t?

[Fire.Effect]

Careful lads.
That's a roof with a steep slope

[annie]

They don’t seem to have any problem walking and standing on that “sloppy roof” 😶

[Lydok]

@4:50 NOW you need to setup a solid perimeter around the building?!?! How about you did this BEFORE Donald Trump nearly got assassinated?

[heitorq]

My driveway has more slope than that roof. It's a miracle I'm alive.

[liberty-matrix]

Everyone admits that not covering the rooftop was a colossal failure. But how did a 20 yr. old kid know to exploit that failure? It only works if it was planned.

[jamesbowman]

My 80 year old mother could walk on that roof.

[cowelk]

Notice the water tower in the background. If a Secret Service sniper had been at the water tower then two people would still be alive and three others would not have been wounded. Who ever was in charge of the security for this even should resign, also.

[ColeFelix]

I don't know about anybody else but I feel like this made our country look like a joke.

[LukeyLukeFairchild-eyct]

It's DISGUSTING Whats going on in the US Government!!

[rickseverythingiracing]

That body has more security than trumps rally had.

[shqueeblesmckloofin]

Incompetence is Treason. Complicity is Treason.

[dashcan]

the murderer of Capt Corey Comporatore

[kittyjo]

Its weird and scary that I've been seeing more news and info from Australia than we do in the US! WTF!? How is this possible??

[SomeDuder]

The #1 question everyone should be pressing...

If they knew of a suspicious person and they lost sight of him, the danger level was increasing, why didn't they pull Trump off the stage? Why did they even let him get on the stage to begin with?
