By COLLEEN LONG and LINDSAY WHITEHURST (Associated Press) WASHINGTON — When the Justice Department was announcing the highest-profile prosecution in its history in Washington, Attorney General Merrick Garland was 100 miles away, meeting with local police in Philadelphia. He stepped outside briefly to speak about how the decision to indict Donald Trump for conspiracy to overturn the 2020 election came from career prosecutors and was led by a special counsel committed to “accountability and independence.” In other words, this wasn’t about politics. Try as Garland might, though, there is no escaping the politics of the moment when the Justice Department of a president who is running for reelection is indicting his chief political rival, the front-runner for the Republican nomination. And though he has distanced himself from the investigation since he appointed special counsel Jack Smith 10 months ago, Garland has the last word on matters related to the prosecution of Trump as long as he is the attorney general. The Justice Department is facing its biggest test in history — navigating unprecedented conditions in American democracy while trying to fight back against relentless attacks on its own credibility and that of the U.S.
