Rudy Giuliani, the president's personal lawyer involved in pressures on Ukraine to investigate Joe Biden, said he would not comply with a citation from the House intelligence committee.
"The position I am declaring now is the position of the administration," Giuliani told The Washington Post.
Giuliani said the White House has written a letter stating that the congressional committee is illegitimate.RELATED
"I would not testify before that committee until there is a vote of Congress and President Adam Schiff is retired," says Giuliani.
Giuliani has until October 15 to deliver relevant materials for the political trial investigation. If he doesn't comply, Democrats will probably argue that it is one more proof of obstruction by the Trump White House.
The news of Giuliani comes after the Trump administration prevented the key witness, US diplomat in Europe Gordon Sondland, testifying before Congress on Tuesday.
Democrats are considering these information blocks as "obstruction of political trial investigation," which may be an impeachment article.
Meanwhile in the Senate, Republican Trump ally Lindsey Graham said he would invite Giuliani to appear before his panel to testify on "corruption and other irregularities involving Ukraine."
