---President Elect Musk and Convicted Felon Donald J Trump---

WASHINGTON (AP) — Former President Donald Trump faces the most urgent legal challenge of his life this week in New York, where he’s set to be arraigned Tuesday on charges arising from hush money payments during his 2016 campaign.

But as much as the attention will be on the courthouse in lower Manhattan, investigations from Atlanta to Washington will press forward, underscoring the broad range of peril he confronts as he seeks to reclaim the presidency.

The vulnerability Trump faces in Washington alone has become clear over the past month, as judges in a succession of sealed rulings have turned aside the Trump team’s efforts to block grand jury testimony from witnesses — including from his own lawyer and his former vice president — who were or still are close to him and who could conceivably offer direct insight into key events.

The rulings directing advisers and aides to testify don't suggest that the Justice Department is close to bringing criminal charges, nor do they guarantee that prosecutors can secure testimony valuable to a potential prosecution. But they're nonetheless a key, closed-door win for the government as it investigates whether classified documents were criminally mishandled at Trump's Florida home and the possible obstruction of that probe, as well as efforts by Trump and his allies to undo the results of the 2020 presidential election.

“I do think when you're talking about an attempted insurrection and the kinds of issues that we're talking about there, there's going to be a lot of arguments on DOJ's side” to get the testimony, said Randall Eliason, a former federal prosecutor and a George Washington University law professor.

Meanwhile, the district attorney in Atlanta is continuing to investigate attempts by Trump and his allies to undo his election loss in Georgia. A special grand jury in February said it believed “one or more witnesses” committed perjury and urged local prosecutors to bring charges.

The former president never testified before the special grand jury, meaning he is not among those who could have perjured themselves. But the report doesn’t foreclose the possibility of other charges, and the case still poses particular challenges for Trump, in part because his actions in Georgia were so public.

Overall, the number of sealed disputes over the scope of grand jury testimony is unusual but perhaps befitting for hugely consequential probes like one concerning a former president. It also stands in contrast to the last special counsel investigation involving Trump, when he was president and when Robert Mueller and his team of prosecutors sought to determine whether Trump's 2016 campaign had colluded with Russia to tip the election.

In that probe, a lawyer inside the White House, Ty Cobb, facilitated voluntary interviews of White House staff — without subpoenas — in hopes that cooperation would hasten the investigation toward conclusion.

“If I could figure out a way to cooperate and still preserve executive privilege, it would speed things up, which in my judgment ... was imperative to the president and to the country,” Cobb said in a recent interview. “We were able to accelerate getting them all of the information.”

Trump in that investigation was protected by the power of his office and by Justice Department legal opinions that say a sitting president cannot be indicted. No longer president, Trump has lost that shield, raising the stakes of his criminal exposure. And as prosecutors have sought to question people close to him — whether to better understand Trump's state of mind and possible defenses, or to gather potentially damaging testimony — Trump's lawyers have repeatedly objected, often in vain.

Perhaps the most vivid example came last month when the then-chief judge of the D.C. federal court ordered that Trump's lawyer, M. Evan Corcoran, had to give more grand jury testimony in the Mar-a-Lago investigation. He had invoked attorney-client privilege in an earlier appearance before the grand jury in declining to answer more questions, but prosecutors pressed for more testimony.

They cited what's known as the crime-fraud exception to attorney-client privilege, which allows prosecutors to compel testimony from a lawyer if they can convince a judge that a client was using legal services in furtherance of a crime. U.S. District Judge Beryl Howell ruled that Corcoran had to return before the grand jury, and he was in court a week later.

Another instance came last week when a different federal judge, James Boasberg, ruled that former Vice President Mike Pence had to give some testimony in a Justice Department special counsel probe into efforts to undo the election.

The decision rejected the Trump team's objections on executive privilege grounds, though Boasberg did give Pence a victory by accepting his lawyers' arguments that, for constitutional reasons, he could not be questioned about his actions on Jan. 6, 2021, when a mob of Trump’s supporters stormed the U.S. Capitol as Republican Pence was presiding over a joint session of Congress to certify Democrat Joe Biden’s victory.

A Trump spokesman did not respond to a request for comment on this story but responded to the ruling in the Pence matter in a statement saying that the Justice Department “is continuously stepping far outside the standard norms in attempting to destroy the long accepted, long held, Constitutionally based standards of attorney-client privilege and executive privilege.”

Other former Trump aides, including Stephen Miller and former national security adviser Robert O'Brien, have also recently been ordered by a judge to offer testimony despite Trump team objections of executive privilege.

The ability of Justice Department prosecutors in multiple instances to convince judges that there's a basis to secure the testimony is significant to the extent that it shows that “there's a there there” with respect to the investigations, Eliason said.

But he cautioned from reading too much into it, given that the threshold for prevailing in a fight over executive privilege or attorney-client is lower than the burden needed to win a criminal case at trial.

“It’s a far cry from being able to prove guilt beyond a reasonable doubt in a contested trial,” Eliason said. “It would be quite a leap to go from there and be able to say that they've got a criminal case locked up.”

In an all-caps post to his social media platform Tuesday, a few hours before he was set to be arraigned, Donald Trump called for his hush-money case to be moved out of Manhattan.

“VERY UNFAIR VENUE, WITH SOME AREAS THAT VOTED 1% REPUBLICAN,” Trump wrote.

The former president, who is running for the Republican presidential nomination again, suggested instead his case should be moved to the more Republican-friendly Staten Island.

“WOULD BE A VERY FAIR AND SECURE LOCATION FOR THE TRIAL,” Trump wrote.

He also reiterated his attacks on New York Supreme Court Justice Juan Merchan, the judge who is handling his case.
