President Trump has filed a lawsuit in federal court seeking to keep two banks from responding to congressional subpoenas, setting up a legal showdown with Democrats eager to investigate his finances.

The president, his three oldest children and his business, The Trump Organization, say the investigations by the House intelligence and Financial Services committees are overbroad and serve no purpose beyond harassment.

The House Judiciary Committee launched a broad investigation into President Trump's inner circle Monday, targeting figures who have worked in his administration and for the Trump Organization businesses.

Michael Cohen was just the beginning.

President Trump's former personal lawyer named names when he testified before the House oversight committee on Wednesday. He told the panel about Trump Organization personnel with knowledge of what Cohen alleged are criminal or questionable actions within the business.
