Factbox: Trump stonewalls House Democrats on multiple probes

President Donald Trump is flatly refusing to cooperate in numerous U.S. congressional probes of himself and his administration, taking a defiant stance that could trigger protracted court fights with House of Representatives Democrats. In an unprecedented step, the Trump administration has filed a lawsuit to try to block one congressional subpoena; some Trump advisers have been told to ignore other subpoenas; and a request for Trump’s tax returns has not been fulfilled. In most instances, Trump risks trouble with Congress over subpoenas, “contempt of Congress” citations and civil enforcement actions in court. Trump’s stonewalling has hardened since the release last week of a redacted report from Special Counsel Robert Mueller on the investigation of Russian interference in the 2016 U.S. presidential election.
