New York Attorney General Letitia James has turned up the heat on former President Trump, announcing Tuesday that her office has opened a criminal investigation into the Trump Organization.

Ms. James has been investigating whether the former president, a known liar, falsely reported his property values to obtain loans and gain tax breaks and other economic benefits.

Ms. James’ office had been looking into the Trump family-owned businesses for any civil violations after Mr. Trump’s former lawyer, fixer and flunky, Michael Cohen, testified before Congress that the former president’s financial statements were manipulated to reduce his real estate taxes and secure loans.

Her new criminal probe is being conducted with some overlap of a similar criminal investigation by the Manhattan District Attorney’s Office of Mr. Trump’s business dealings before his presidency, including tax and insurance fraud and falsification of business records.

This bigger investigation by Ms. James’ office escalates Mr. Trump’s possible legal jeopardy, in which prison time — and not simply a civil fine — is part of the picture.

Earlier this year, prosecutors in Fulton County, Ga., opened a criminal investigation into Mr. Trump’s attempt to influence that state’s presidential election results. The former president was recorded in a phone call on Jan. 2 badgering Georgia’s secretary of state to overturn that state’s presidential election victory for Democrat Joe Biden by finding 11,000 more votes for Mr. Trump.

We believe the only thing upsetting Mr. Trump more than the announcement of this new criminal probe is that a Black woman is in charge of it. A Black woman also is in charge of the criminal probe in Fulton County, Ga.

We have only one comment for Ms. James and the New York and Georgia prosecutors: Go get ’em.
