Donald Trump returns to his comfort zone — filing lawsuits to shield his wrongdoing

On Monday, the Trump family launched a lawsuit against Deutsche Bank and Capital One to prevent the financial institutions from divulging information about Trump's finances to Congress.

Rolling Stone observed that the move is well within Donald Trump's comfort zone.

"As the Democrats controlling the House of Representatives grow more comfortable with their power to investigate, President Donald Trump is leaning on the same tactic he favored for decades as Shady Real Estate Developer Trump: filing lawsuits," Rolling Stone noted.

The lawsuit directly challenges the congressional subpoenas issuing from multiple investigations into wrongdoing by the Trump administration.

"This case involves congressional subpoenas that have no legitimate or lawful purpose,” the suit begins. “The subpoenas were issued to harass President Donald J. Trump, to rummage through every aspect of his personal finances, his businesses and the private information of the president and his family, and to ferret about for any material that might be used to cause him political damage," the lawsuit asserts.

"No grounds exist to establish any purpose other than a political one.”

The lawsuit is the latest way Trump is trying to thwart congressional probes, despite continuing to claim that he didn't obstruct Special Counsel Robert Mueller's investigation.

The president's antipathy towards congressional oversight has frustrated Democrats and led legal analysts to fear that he's subverting the checks and balances of US government.
