Former President Donald Trump is tied up in a number of legal woes, and it appears criminal charges may finally be coming.

The first potential indictment could come from prosecutors in New York over hush money payments made to adult entertainment star Stormy Daniels ahead of the 2016 election to keep quiet about an alleged affair between Trump and Daniels. Trump has denied the affair and knowledge of the $130,000 payment.

Trump and his team have been invited to testify before a grand jury, but legal experts on Greater Boston said it's highly unlikely that Trump will testify.

Ron Sullivan, director of the Criminal Justice Institute at Harvard University, said it would be a "disaster" for Trump to go under oath in front of a grand jury, knowing that he can be hard to control.

Sullivan said it appears Trump is running out of time to escape the many legal woes swirling around him.

"I do think that the investigations are just — all of them seem to be approaching the end stage so, you know, the dominoes are going to start falling one after another," Sullivan said.

Trump is also implicated in investigations related to the January 6 insurrection, tax evasion, election interference and more. It's a longstanding norm in American politics not to indict a presidential candidate due to charges of being political and lacking fairness.

Former Assistant U.S. Attorney Dan Small said prosecutors should hurry with the indictments. "No prosecutor wants to indict a political candidate in an election year," he said. "They really have to make the decision within the next seven months."
