parliament portrayed as a chamber full of squabbling chimpanzees not the latest prank to debate but a 10 year old painting by the anonymous art superstar banksy the work bench to record 11000000 euro as. i'm irish waiter thank you for joining us for the 1st time the impeachment inquiry into u.s. president donald trump has reached directly to the white house democratic lawmakers have subpoenaed officials to force the release of documents relating to trump's contacts with ukraine including his call in july with ukraine's president vladimir selenski several house committees are looking into whether trump pressured ukraine to investigate former democrat vice president joe biden trump has vowed not to cooperate with the probe. and joining us for more on this story is g.w. correspondent all of us sal in washington d.c.

so all over what do we think house investigators are expecting to learn from these documents. we're in the middle of an impeachment inquiry and so what the investigators and the committees in particular are trying together here is to get as much material evidence records as possible to be able to eventually decide whether or not to move forward and launch an official impeachment proceeding that has of course not happened yet and so what they did with the subpoena here today is basically to try to force the white house to release all records they have with regards to that phone call made between president trump and the ukrainian president selenski here before that committee's role to have written 2 letters to the wide holes that were both ignored they were not replied to and so now all these 3 committees that are investigating here came together issued that subpoena and that

can be regarded on impreza dented move in a serious escalation here between congress and the white tells now trump has been staunchly maintaining he's not going to play nice what could happen if the white house continues to ignore these committees and ignores the subpoena. what was different this time around is that the nature of the subpoena is legally binding so technically scene the white house has to comply now and the committees have made very clear what their standpoint is you know they wrote in a letter to the chief of staff mulvaney of the wide tells that if they don't comply that would be considered off structuring the impeachment inquiry struction of justice of course which is illegal so we might even in a potentially further escalation here see legal steps taken against the wide tells and president trump has made clear that he will not deliver any material until the impeachment proceedings have been started so we might see a real shoulder on here soon between congress and the white house for us in
