U.S. President Donald Trump pledged to “expose” his enemies during a norm-breaking political speech at the Justice Department in which he aired a litany of grievances against the criminal cases he faced and vowed retribution for what he described as the “lies and abuses that have occurred within these walls.”

The speech was meant to rally support for Trump administration policies on violent crime, drugs and illegal immigration. But it also functioned as a triumphant forum for the president to boast about having emerged legally and politically unscathed from two federal prosecutions that one year ago had threatened to torpedo his presidential prospects but were dismissed after his election win last fall.

Though other presidents have spoken from the Justice Department’s ceremonial Great Hall, Trump’s address amounted to an extraordinary display of partisan politics and personal grievance inside a Justice Department that is meant to be blind to both. He promised to target his perceived enemies even as he claimed to be ending what he called the weaponization of the department.

The speech marked the latest manifestation of Trump’s unparalleled takeover of the department and came amid a brazen campaign of retribution already undertaken under his watch, including the firing of prosecutors who investigated him and the scrutiny of agents who investigated supporters who stormed the U.S. Capitol on Jan. 6, 2021.

“Our predecessors turned this Department of Justice into the Department of Injustice. But I stand before you today to declare that those days are over, and they are never going to come back and never coming back,” Trump said to cheers from a crowd that included political allies. “So now, as the chief law enforcement officer in our country, I will insist upon and demand full and complete accountability for the wrongs and abuses that have occurred.”

The visit to the Justice Department, the first by Trump and the first by any president in a decade, brought him into the belly of an institution he has disparaged in searing terms for years but one that he has sought to reshape by installing loyalists and members of his personal defense team in top leadership positions.

Trump’s unique status as a onetime criminal defendant indicted by the department he was now addressing hung over the speech as he vented, in profane and personal terms, about investigations as far back as the Russian election interference investigation to the more recent inquiries into his efforts to overturn the 2020 presidential election and the hoarding of classified documents at his Mar-a-Lago estate.

“We will expel the rogue actors and corrupt forces from our government. We will expose, very much expose their egregious crimes and severe misconduct,” Trump said in a wide-ranging speech that touched on everything from Russia’s war against Ukraine to the price of eggs.

“It’s going to be legendary. And going to also be legendary for the people that are able to seek it out and bring justice. We will restore the scales of justice in America, and we will ensure that such abuses never happen again in our country.”

Trump’s visit also comes at a time when Attorney General Pam Bondi has asserted that the department needs to be depoliticized even as critics assert agency leadership is injecting politics into the decision-making process.

The relationship between presidents and Justice Department leaders has waxed and waned over the decades depending on the personalities of the officeholders and the sensitivity of the investigations that have dominated the day. The dynamic between President Joe Biden, a Democrat, and his attorney general, Merrick Garland, was known to be fraught in part because of special counsel investigations that Garland oversaw into Biden’s mishandling of classified information and into the firearms and tax affairs of his son Hunter.

When it comes to setting its agenda, the Justice Department historically takes a cue from the White House but looks to maintain its independence on individual criminal investigations.

Trump has upended such norms.

He encouraged specific investigations during his first term and tried to engineer the firing of Robert Mueller, the special counsel assigned to investigate ties between Russia and Trump’s 2016 campaign. He also endured difficult relationships with his first two handpicked attorneys general -- Jeff Sessions was fired immediately after the 2018 midterm election, and William Barr resigned weeks after publicly disputing Trump’s bogus claims of widespread fraud in the 2020 election.

Arriving for a second term in January fresh off a landmark Supreme Court opinion that reaffirmed a president’s unshakable control of the Justice Department, Trump has appeared determined to clear from his path any potential obstacles, including by appointing Bondi -- a former Florida attorney general who was part of Trump’s defense team at his first impeachment trial -- and Kash Patel, another close ally, to serve as his FBI director.

At her January confirmation hearing, Bondi appeared to endorse Trump’s false claims of mass voter fraud in 2020 by refusing to answer directly whether Trump had lost to Biden. She also echoed his position that he had been unfairly “targeted” by the Justice Department despite the wealth of evidence prosecutors say they amassed. She regularly praises him in Fox News Channel appearances and proudly noted that she had removed portraits of Biden, Garland and Vice President Kamala Harris from a Justice Department wall upon arriving.

“We all adore Donald Trump, and we want to protect him and fight for his agenda. And the people of America overwhelmingly elected him for his agenda,” Bondi said in a recent Fox interview with Trump’s daughter-in-law Lara Trump.

Even before Bondi had been confirmed, the Justice Department fired department employees who served on special counsel Jack Smith’s team, which charged Trump with plotting to overturn the 2020 election and with hoarding classified documents at Mar-a-Lago. Both cases were dismissed last November in line with longstanding Justice Department policy against indicting sitting presidents.

Officials also demanded from the FBI lists of thousands of employees who worked on investigations into the Jan 6, 2021, riot at the U.S. Capitol, when a mob of Trump’s supporters stormed the building in an effort to halt the certification of the electoral vote, and fired prosecutors who had participated in the cases. And they’ve ordered the dismissal of a criminal case against New York Mayor Eric Adams by saying the charges had handicapped the Democrat’s ability to partner in the Republican administration’s fight against illegal immigration.
