President Trump is digging in once again to keep his tax records out of the hands of New York State prosecutors.

In a court filing on Wednesday, Trump and Manhattan District Attorney Cyrus Vance Jr. presented dueling arguments over a subpoena for the president’s financial records, which are held by the U.S. branch of Mazars, a Paris-based accounting firm.

“Trump recently lost his bid to have the grand jury subpoena tossed on the grounds that as sitting president he has absolute immunity from state court proceedings,” says the Washington Post, noting that last week’s 7-2 Supreme Court decision favored Vance.

The subpoena in question involves Vance’s investigation of Trump and his business “over hush money payments made to two women during the 2016 presidential campaign, including to pornography actress Stormy Daniels,” the Post says.

Despite euphoric tweets from some Trump opponents, the new legal proceeding is certain to delay any resolution of the subpoena dispute, and time is not on Vance’s side.

“Vance’s office told the court that the case should proceed quickly because of ‘continuing concerns about the potential loss of critical evidence and expiration of statutes of limitations,’” reports USA Today.

The federal judge in the case “ordered a hearing to be held July 16 [Thursday] on whether [Trump] has additional arguments,” says Bloomberg News.
