The top Democrat on the US House Intelligence Committee said on Tuesday the panel should begin contempt proceedings if Steve Bannon, a former adviser to President Donald Trump, continues to refuse to testify in an investigation of Russian Federation and the 2016 presidential election.
Bannon though is likely to defer to President Donald Trump on the scope of his testimony.
"We've got all the tools the House has to enforce subpoenas", Conaway said.
But the negotiations between the committee and the White House have reportedly stalled, as President Donald Trump's office will only permit Bannon to answer fourteen simple "yes" or "no" questions, the Associated Press reported.
Congressman Mike Conaway, the Texas Republican leading the panel's investigation into Russian interference into the 2016 USA presidential election, said he had expected Bannon to appear to answer questions, but Bannon was a no-show, part of lawmakers' ongoing dispute with the White House over the scope of their questioning of Bannon.
"Our subpoenas have to matter", Republican Rep. Tom Rooney, a member of the House intelligence panel, told reporters.
Bannon's interview has been delayed until next week.
The committee, in light of Bannon's expected absence, could move to hold him in contempt, beginning a process that could end in a full House vote authorizing GOP leaders to seek criminal charges against Bannon. During his January 16 appearance, Bannon refused to answer questions about his time in President Donald Trump's administration or the post-election presidential transition, committee members said.
Committee Republicans said Bannon's appearance was postponed at the committee's initiative. Members of the committee have said privilege would not apply.
The top Democrat on the U.S. House Intelligence Committee described on Wednesday "a developing pattern" in which witnesses have declined to discuss events occurring after President Donald Trump's election in the panel's probe of Russian Federation and the 2016 vote.
Schiff said the White House position on Bannon's testimony "covers matters during the transition" before Trump's assumption of power a year ago, Bannon's seven months at the White House, and his communications with Trump since leaving government service last August, "even though the president has not in fact invoked executive privilege" to bar Bannon's testimony.
One of the people says Bannon plans to tell Mueller "everything" he knows.
The White House and the president's legal team have not responded to requests for comment.
