The civil fraud trial that kicked off against Donald Trump this week in a New York courtroom is just one of many legal problems facing the former president as he campaigns for a return to the White House.

The judge overseeing the case, Arthur Engoron, resolved the lawsuit's top claim before the trial even began, ruling that Trump routinely deceived banks, insurers and others by exaggerating the value of assets on paperwork used in making deals and securing loans. Engoron will decide on six remaining claims in New York Attorney General Letitia James' lawsuit, including allegations of conspiracy, falsifying business records and insurance fraud.

Trump is also facing 91 felony counts in four criminal cases in Washington, New York, Florida and Georgia and could potentially be looking at years in prison if convicted.

Here's a look at some of the other top probes against Trump:

CLASSIFIED DOCUMENTS CASE

Special counsel Jack Smith has been leading two federal probes related to Trump, both of which have resulted in charges against the former president.

The first charges to result from those investigations came in June when Trump was indicted on charges he mishandled top secret documents at his Florida estate. The indictment alleged that Trump repeatedly enlisted aides and lawyers to help him hide records demanded by investigators and cavalierly showed off a Pentagon "plan of attack" and classified map.

A superseding indictment issued in July added charges accusing Trump of asking for surveillance footage at his Mar-a-Lago estate to be deleted after FBI and Justice Department investigators visited in June 2022 to collect classified documents he took with him after leaving the White House. The new indictment also charged him with illegally holding onto a document he's alleged to have shown off to visitors in New Jersey.

In all, Trump faces 40 felony charges in the classified documents case. The most serious charge carries a penalty of up to 20 years in prison.

Walt Nauta, a valet for Trump, and Carlos De Oliveira, the property manager at Trump's Florida estate, have been charged in the case with scheming to conceal surveillance footage from federal investigators and lying about it.

Trump, Nauta and De Oliveira have pleaded not guilty.

U.S. District Judge Aileen Cannon set a trial date of May 20, 2024. If that date holds, it will mean a possible trial will not start until deep into the presidential nominating calendar and probably well after the Republican nominee is clear — though before that person is officially nominated at the Republican National Convention.

ELECTION INTERFERENCE

Smith's second case against Trump was unveiled in August when the former president was indicted on felony charges for working to overturn the results of the 2020 election in the run-up to the violent riot by his supporters at the U.S. Capitol on Jan. 6, 2021.

The four-count indictment includes charges of conspiracy to defraud the United States government and conspiracy to obstruct an official proceeding: the congressional certification of Joe Biden's victory. It describes how Trump repeatedly told supporters and others that he had won the election, despite knowing that was false, and how he tried to persuade state officials, then-Vice President Mike Pence and finally Congress to overturn the legitimate results.

After a weekslong campaign of lies about the election results, prosecutors allege that Trump sought to exploit the violence at the Capitol by pointing to it as a reason to further delay the counting of votes that sealed his defeat.

In their charging documents, prosecutors referenced a half-dozen unindicted co-conspirators, including lawyers inside and outside of government who they said had worked with Trump to undo the election results and advanced legally dubious schemes to enlist slates of fake electors in battleground states won by Biden.

The Trump campaign called the charges "fake" and asked why it took 2 1/2 years to bring them. He has pleaded not guilty.

The case is set for trial March 4, 2024, in federal court in Washington.

HUSH MONEY SCHEME

Trump became the first former U.S. president in history to face criminal charges when he was indicted in New York in March on state charges stemming from hush money payments made during the 2016 presidential campaign to bury allegations of extramarital sexual encounters.

He pleaded not guilty to 34 felony counts of falsifying business records. Each count is punishable by up to four years in prison, though it's not clear if a judge would impose any prison time if Trump were convicted.

The counts are linked to a series of checks that were written to his lawyer Michael Cohen to reimburse him for his role in paying off porn actor Stormy Daniels, who alleged a sexual encounter with Trump in 2006, not long after Melania Trump gave birth to their son, Barron. Those payments were recorded in various internal company documents as being for a legal retainer that prosecutors say didn't exist.

The former president is next set to appear in state court on Jan. 4, before Republicans begin their nominating process in earnest.

GEORGIA

Trump is charged alongside 18 other people — including former New York Mayor Rudy Giuliani and former White House chief of staff Mark Meadows — with violating the state's anti-racketeering law by scheming to illegally overturn his 2020 election loss.

The indictment, handed up in August, accuses Trump or his allies of suggesting Georgia's Republican secretary of state could find enough votes for him to win the battleground state; harassing an election worker who faced false claims of fraud; and attempting to persuade Georgia lawmakers to ignore the will of voters and appoint a new slate of Electoral College electors favorable to Trump.

One defendant, bail bondsman Scott Graham Hall, pleaded guilty last Friday in a plea deal with prosecutors and agreed to testify in further proceedings. The other 18 defendants, including Trump, have pleaded not guilty.

Two of them, lawyers Sidney Powell and Kenneth Chesebro, are scheduled to go on trial later this month. A trial date for Trump and the others has not yet been set.
