Trump sues Deutsche Bank and Capital One over Democrat subpoenas

US President Donald Trump has sued two banks in a bid to stop them handing over his financial records to Congress.

The lawsuit against Deutsche Bank and Capital One was filed after Democrat-led committees issued subpoenas for information on his finances.

His three eldest children and the Trump Organisation joined the lawsuit, which argues there are no legitimate grounds for investigating his business affairs.

Leading Democrats said they would not be deterred by the blocking attempt.

A Deutsche Bank spokeswoman told the New York Times: "We remain committed to providing appropriate information to all authorized investigations"

There was no immediate comment from Capital One.

The lawsuit was filed in New York on Monday and aims to block the banks from complying with the subpoenas issued by the Democrat-controlled Congress, which is investigating the Trump family's financial dealings.

Both banks are involved with Mr Trump's real estate projects.

The filing says the subpoenas "have no legitimate or lawful purpose".
