Sen. Josh Hawley, R-Mo., is urging Department of Homeland Security (DHS) Secretary Kristi Noem to declassify all documents related to the assassination attempt on then-presidential candidate Donald Trump in Butler, Pennsylvania, on July 13, 2024.

Hawley’s request comes a year after 20-year-old Thomas Matthew Crooks fired off several shots at Trump from a rooftop near the presidential rally grounds. The gunman had a clear shot and grazed the president’s ear.

Even after a year, though, questions still remain about how Crooks was able to get a clear shot.

In his letter to Noem, Hawley mentions the one-year anniversary of the first assassination attempt on Trump.

"This occasion marks a deeply troubling chapter in our nation’s history and serves as a reminder of the importance of transparency in preserving public trust during moments of national crisis," he wrote. "To that end, I urge you to take the necessary steps to declassify all documents within the Department of Homeland Security (DHS) related to the events of July 13, 2024.

"As you know, assassination attempts against current and former presidents are rare but profoundly consequential events in American life," Hawley continued. "And the American people rightly expect full transparency from their government."

The senator pointed to investigation stonewalling tactics from the Biden administration’s Secret Service and DHS, which he said ultimately denied basic facts to the American people.

"The public learned far more from whistleblowers than they did from public officials, and I released a report documenting these disclosures, many of which have been corroborated to date," Hawley wrote. "In October of last year, in a unanimous vote, the Homeland Security Committee passed my legislation requiring the Secret Service release to the public all pertinent documents.

"Now, I am requesting that you immediately declassify and release all documents relating to the first assassination attempt on President Trump within the full extent of your authority, subject only to the narrowest possible redactions necessary to protect ongoing operations or individual safety," he said. "The public deserves a full and accurate account of this event, the circumstances that allowed it to happen, and the steps the government has taken since to strengthen protective measures."

Hawley requested a complete inventory of all classified or non-public materials related to the first assassination attempt on Trump, including reports, internal communications, threat assessments, after-action reviews and coordinated records with other agencies.

He also requested a formal explanation for the continued classification of materials Noem believes must remain restricted, as well as a proposed plan and timeline for the immediate declassification and public release of all remaining documents, all by July 30, 2025.

Fox News Digital has reached out to DHS for comment on the matter.

Hawley released a report in September, detailing the failures of the Secret Service in connection with the attempted assassination of Trump in July, which included whistleblower allegations that are "highly damaging to the credibility" of the agency.

The report uncovered a "compounding pattern of negligence, sloppiness, and gross incompetence that goes back years, all of which culminated in an assassination attempt that came inches from succeeding."

Hawley accused the Secret Service, FBI and DHS of all trying "to evade real accountability."

"These agencies and their leaders have slow-walked congressional investigations, misled the American people, and shirked responsibility," the report states. 

After the first of two assassination attempts against Trump in just over two months, Hawley visited the Butler rally site to interview whistleblowers and opened up a whistleblower tip line, encouraging those with relevant information to share with officials. 

Documents subpoenaed by the Senate Committee on Homeland Security and Government Affairs also show major failures among the six U.S. Secret Service (USSS) agents who were suspended without pay in response to the assassination attempt.

The documents were based on interviews with the agents and their colleagues and revealed that several agents admitted the existence of major security concerns at the Butler rally, but none of them elevated the concerns or helped produce a plan to properly cover the roof that provided Crooks a clear shot of Trump.

The documents show that some agents in charge never even conducted walk-throughs of the site. For example, the lead advance agent, documents show, never did a final security walk-through of the rally site because she was in the hospital for heat exhaustion, the special agent in charge said when questioned.

Some of the agents were suspended without pay for various terms, though none of the agents were fired.

NATO Secretary General Mark Rutte said the White House’s decision to sell weapons to NATO countries for distribution to Ukraine was a "significant" moment for Europe amid stalled peace negotiations to end Russia’s war.

Rutte met with President Donald Trump Monday in Washington, D.C., where the commander-in-chief announced the sale of billions of dollars worth of weapons, including Patriot air defense missile systems, and threatened 100% secondary tariffs on countries that trade with Russia if a deal isn’t made within 50 days.

"This is significant," Rutte said on "Special Report." "So today, if you are in Beijing, or in Delhi, or you're in Brazil and you know that this is coming to you, you might want to call Vladimir Vladimirovich Putin and say, ‘Hey, friend, we are still buying stuff from you, but you have got to get serious when it comes to these negotiations on the ceasefire or a peace deal, or otherwise we get hit by the secondary sanctions.’"

TRUMP'S BOLD PIVOT ON UKRAINE SENDS MAJOR SIGNAL 

Sen. Lindsey Graham, R-S.C., said China, India and Brazil buy oil and petroleum products from Russia, helping prop up its war machine.

Trump has held off on imposing additional sanctions on Moscow, preferring to wait and see if his diplomatic efforts will bear fruit. He has grown frustrated with Russian President Vladimir Putin, who has refused to agree to a 30-day unconditional ceasefire proposed by the United States and its European allies earlier this year.

"If we don't have an agreement in 50 days, that's what we're doing, secondary tariffs, and they're biting. And I hope we don't get to the point where we do, but I've been hearing so much talk. It's all talk. It's all talk, and then missiles go into Kyiv and kill 60 people. It's got to stop," Trump said Monday from the Oval Office.

Putin has escalated attacks on Ukraine in recent months, targeting Kyiv with large-scale missile and drone attacks. The Russian strongman has stuck to his maximalist demands during two rounds of peace talks in Istanbul that have failed to produce much other than prisoner of war exchanges.

Rutte told Fox News chief political anchor Bret Baier that the weapons sales send a clear message to Putin about the unity between the United States and Europe and how the two will "do whatever it takes for Ukraine."

"If I was in the Kremlin today, I would not be too happy because this is a clear signal that President Trump is serious. He wants peace. He hates the fact that so many people lose their lives in Ukraine," said the former prime minister of the Netherlands.

SENATE MOVES TO REIGN IN TRUMP ADMINISTRATION'S FLUCTUATING UKRAINE POLICY

Trump has set multiple two-week deadlines for Russia to advance peace talks with Ukraine, but they’ve repeatedly expired without significant progress or consequences.

Ukraine’s former Foreign Minister Dmytro Kuleba called on Trump last month to reshuffle three things to revitalize the negotiating process: sticks, carrots and the pressure of time. 

Kuleba said Trump created the pressure of time by stating he could end the war in 24 hours and calling on both sides to sit down and negotiate.

"What happened next is that all sticks went to Ukraine and all carrots went to Russia. It has never worked like this centuries ago in the history of diplomacy. It doesn't work like this, and it's not going to work like this, OK, because the right way to do it is to create a pressure of time to avoid endless deliberations and to find the right balance of sticks and carrots for each side," he said.
