Members of the bipartisan Trump Assassination Task Force are traveling to Butler, Pennsylvania, to demand answers as the Secret Service continues to “drag” information.

Spokesman Mike Johnson previewed the trip on Fox & Friends Monday morning, saying he has “confidence” in the head of the task force, Republican Rep. Mike Kelly of Pennsylvania, who is “doing a great job.”

“They have investigated, sought answers and requested documents. They have been slow to move forward, that is the problem. That is why we are pushing to get answers for the American people,” the spokesman said.

DailyMail.com has learned that Kelly and Jason Crow (D-Colorado), a senior member of the task force, plan to meet with local law enforcement to obtain “first-hand information” relevant to their extensive investigation.

Her trip to Butler comes just days after several Secret Service agents were placed on leave pending the investigation into the assassination attempt on Donald Trump.

The massive security failure that led to the horrific incident has sparked investigations by a variety of government agencies that are still ongoing after 20-year-old Thomas Matthew Crooks opened fire on the former president on July 13.

Several secret service agents have been placed on leave pending the investigation into the assassination attempt on Donald Trump, reports suggest.

According to NBC News, four Pittsburgh field officials, including the department’s head, and a Trump agent were placed on leave.

House Oversight Committee Chairman James Comer (R-Kentucky) told DailyMail.com on Friday that “the Secret Service’s historic failures must be held accountable.”

“Holding negligent employees accountable is the first step. I look forward to the results of the task force’s investigation. We must ensure that the Secret Service does not fail again.”

Secret Service spokesman Anthony Guglielmi declined to comment on reports that the agents were placed on leave because it was a “personnel matter.”

However, he told DailyMail.com that they are still “investigating the processes, procedures and factors that led to this outage.”

“The U.S. Secret Service expects its personnel to maintain the highest professional standards, and any identified and proven violations of policy will be investigated by the Office of Professional Responsibility and may result in disciplinary action.”

The suspended agents are expected to continue working for the Secret Service and will be paid. They have most likely been reassigned to an administrative role while the investigation continues.

The crooks’ plot led to the resignation of CIA Director Kimberly Cheatle and raised a number of questions, including how he managed to get onto a rooftop in Butler, Pennsylvania, where Trump’s speech there was clearly visible.

The potential assassin was spotted by witnesses before the shooting and the secret service and police were warned of his presence.

Nevertheless, he was able to open fire at least eight times with the AR rifle he had received from his father.

Republican Rep. Mike Waltz told DailyMail.com earlier this week he was not convinced the crooks acted alone.

He said the shooter’s motive was still unknown and he feared a foreign entity or other third party may have been involved in the attack.

Waltz asked how the feds could say with certainty that Crooks was a loner when they couldn’t answer other questions, such as why he had multiple encrypted messaging accounts abroad.

His comments came after it was revealed that Iran was also planning an attempt on the former president’s life around the same time Crooks was carrying out his plan.

“The deeper we dig into this, the more questions I have,” Waltz said. “What’s really disturbing is what’s coming to light.”

“What I find most disturbing is that there are ongoing plots from Iran to kill a former president and leading candidate and that a Pakistani citizen was just arrested after paying a down payment for assassins, and this is barely reported in the news.”

Crooks, 20, managed to create several explosive devices using remote detonators, which also made Waltz suspicious and asked him if he had any help.

Crooks, 20, was shot dead on the spot by U.S. Secret Service after killing one rally-goer, seriously wounding two other supporters and barely grazing Trump’s ear at a rally in Butler, Pennsylvania on July 13.

While the FBI, the US Secret Service (USSS) and the Department of Homeland Security conduct their investigations into the massive security failure, Waltz and twelve other members of a House task force are also investigating the attempted assassination.

“I don’t understand it and don’t have any answers yet to help me understand how the (intelligence) service and DHS came out so quickly and said – and I think the FBI did too, but I have to check that – that he acted alone,” Waltz told DailyMail.com on Wednesday at Trump Tower in Chicago. “How do you know that, just days after you started your investigation?”

The Florida congressman added: “You can’t tell us his motive, but you could tell us he acted alone? You can’t access these encrypted overseas accounts, but you can tell us he acted alone? So I don’t believe that yet.”

A bullet from his AR rifle, which Crooks’ father had legally purchased, grazed the former president’s right ear.

Crooks killed one rally participant and seriously injured two others before he was incapacitated.

The FBI also found explosives in Crooks’ car, which was parked near the rally site. And when they searched his parents’ house, where he lived, they found more bombs.

“I don’t know many 19-year-olds who could build multiple remote-controlled explosive devices,” Waltz told DailyMail.com. “Why wasn’t this picked up when he looked it up online or bought literature about it?”
