Donald Trump is going to court to try to keep his financial records secret. Earlier this month Rep. Elijah Cummings, chairman of the House Oversight and Reform Committee, requested Trump’s accounting firm, Mazars USA, turn over a decade of financial records relating to the president. But today The Washington Post is reporting that Trump is suing Cummings saying:

“President Trump is seeking a court order to prevent his accounting firm from complying with what his lawyers say is an illegitimate use of congressional subpoena power by congressional Democrats.

In a filing Monday morning, the president claims, “Democrats are singularly obsessed with finding something they can use to damage the President politically.”

The lawsuit states:

Because Chairman Cummings’ subpoena to Mazars threatens to expose Plaintiffs’ confidential information and lacks “a legitimate legislative purpose,” this Court has the power to declare it invalid and to enjoin its enforcement.
