It has been just over two weeks since a gunman opened fire on President Donald Trump and killed one of his supporters.

While FBI Director Christopher Wray said last week that his agency is investigating the shooting, members of Congress have stepped in to conduct an investigation of their own. 

Lawmakers travel to Butler, Pennsylvania

According to the Washington Examiner, Homeland Security Committee Chairman Mark Green recently led a group of House Republicans to the shooting site in Butler, Pennsylvania.

Among those demanding answers is Arizona Republican Rep. Eli Crane, a former Navy SEAL who previously served as sniper.

I’m on the roof of the building in Butler, PA where shots were fired in an attempt to assassinate President Trump.

As a former Navy SEAL sniper, it was clear to me that many security measures were dropped making Pres. Trump extremely vulnerable.

Crane posted a video clip of himself on the roof from which would be assassin Thomas Matthew Crooks fired from and made light of a claim from former Secret Service Direct that it was too sloped to secure.

"It's not that steep at all," Crane said of the roof. "We just had a 70-year-old man back here climb up on the roof easily."

Whistleblower: Secret Service refused to deploy drones until after shooting

Another issue is the use of drones, with the Associated Press reporting that the FBI has confirmed Crooks used a drone to surveil the site of Trump's rally.

However, Missouri Republican Sen. Josh Hawley announced in a letter sent last week to Department of Homeland Security (DHS) Secretary Alejandro Mayorkas that he has been told no drones were deployed by the Secret Service.

"According to one whistleblower, the night before the rally, U.S. Secret Service repeatedly denied offers from a local law enforcement partner to utilize drone technology to secure the rally," Hawley wrote.

"This means that the technology was both available to USSS and able to be deployed to secure the site. Secret Service said no," he continued.

Snipers identified Crooks before attack

Hawley went on to add that he was told the Secret Service later "changed course" after the attack and "asked the local partner to deploy the drone technology to surveil the site."

Meanwhile, the Examiner reported that Iowa Republican Sen. Chuck Grassley released bodycam footage in which a Secret Service agent can be seen discussing Crooks after he had been shot.

"So, this is the guy that your snipers saw?" the agent said. A Beaver County Emergency Services Unit officer responded by saying, "Yes, Beaver County snipers seen him and sent pictures out. This is him."
