US president 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 organization 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.
