In the lawsuit against Cummings, Trump's lawyers accused Democrats of being "singularly obsessed with finding something they can use to damage the President politically", and suggested they had no legal authority to issue subpoenas of the president's past business dealings.
The lawsuit charged that the Democrats have weaponized its committees since taking over the House of Representatives against the president.
"We will not allow Congressional Presidential harassment to go unanswered", said Jay Sekulow, counsel to the president.
Last week, Trump lawyer William Consovoy and fellow Trump attorney Stefan Passantino warned accounting firm Mazars USA against complying with an expected subpoena from another House panel, the Oversight and Reform Committee.
The Monday lawsuit argues that the goal of the subpoena is to "expose the plaintiffs' private financial information for the sake of exposure, with the hope that it will turn up something that Democrats can use as a political tool" going into the 2020 election campaign. They accuse Cummings of acting as law enforcement and not as a legislator.
Cummings said during an appearance on CNN on April 19 that Mueller's yearslong investigation wasn't thorough enough and that Congress would need to probe Trump's alleged obstruction efforts further.
