Former President Donald Trump filed a lawsuit against New York Attorney General Letitia James (D) on Monday, claiming her investigation into his business practices violates his constitutional rights, as the ex-president seeks to stem a growing trend of legal problems.

KEY FACTS

James has been overseeing a civil investigation into the Trump Organization to determine whether it purposely undervalued properties, according to reports.

James is reportedly set to subpoena Trump, asking him to appear for a deposition on January 7 as part of the investigation.

The suit was filed in federal court for the Northern District of New York, and news of the lawsuit was first reported by the New York Times.

In a statement, James blasted the lawsuit, saying the Trump Organization has “continually sought to delay our investigation.”

CRUCIAL QUOTE

“To be clear, neither Mr. Trump nor the Trump Organization get to dictate if and where they will answer for their actions,” James said.

KEY BACKGROUND

James' probe is just one of several investigations against the former president and his business associates, though Trump as of yet hasn't been personally accused of any wrongdoing. But in June, the Trump Organization and its former CEO, Allen Weisselberg, were both indicted by a Manhattan grand jury as part of a criminal investigation alleging a 15-year tax evasion scheme that paid company executives $1.7 million million in untaxed money. Another grand jury has convened, reportedly to determine whether criminal charges should be brought as part of the Manhattan DA's criminal investigation into the alleged property value fraud (Full disclosure: Forbes has testified before the grand jury.

Yet another investigation in Westchester County is reviewing financial records from the Trump National Golf Club Westchester to determine if it committed fraud by undervaluing its assets to lower its tax bill.

TANGENT

James ended her bid earlier this month for New York governor, announcing she’ll instead seek reelection for another term as attorney general. James said in a statement that she’s overseeing important cases and that “I intend to finish the job,” appearing, at least in part, to reference the Trump investigation. Trump attacked James after she dropped out of the governor’s race, claiming she wants to “politically weaponize her position as Attorney General.”
