Donald Trump faces the prospect of becoming only the third USA president to be impeached when open hearings begin this week into his alleged effort to bolster his re-election hopes by pushing Ukraine to find dirt on a Democratic rival. Nunes said the president should have the opportunity to confront his accuser.
In addition to Mr. Biden, son of former Vice President Joseph R. Biden and a former board member of Ukraine's Burisma Holdings, the list included former Burisma board member Devon Archer; ex-Democratic National Committee staffer Alexandra Chalupa, and former Fusion GPS opposition researcher Nellie Ohr.
House Republicans released their request for witnesses on Saturday, including Hunter Biden, the son of former Vice President Joe Biden, an individual referred to as "the anonymous whistleblower, "senior diplomat Kurt Volker, Tim Morrison, the senior director for Europe and Russian Federation on the White House National Security Council, and Under Secretary of State for Political Affairs David Hale".
At the same time, Kennedy attacked the Democratic-led impeachment inquiry process as being slanted, pointing to Schiff's reluctance to allow the witnesses Republicans have requested.
One Democratic member of the House Intelligence Committee, also interviewed on Fox, suggested that the main consideration in summoning witnesses should be whether they had "knowledge or evidence about the president's conduct" in regard to Ukraine.
Congressional Republicans have vowed to call the complainant as a witness in impeachment proceedings, but it is unclear whether he will be required to testify, as House Democrats passed rules requiring Schiff to approve all subpoenas and even questions asked of witnesses.
The whistleblower is purported to be a career CIA analyst who worked on the National Security Council during the Obama administration and the initial months of the Trump administration; he now purportedly works on the National Intelligence Council.
He also has said there is no need to hear from the whistleblower because other witnesses broadly have substantiated the complaint. Trump has denied doing anything improper.
The Democrats are aiming to make Trump only the third president in U.S. history to be impeached, which would see him go on trial for removal in the Republican-dominated Senate.
"This is a very strong case of bribery, because you have an elected official, the president, demanding action of a foreign country, in this case. and he is withholding aid", said Speier.
Number one on the list is Hunter Biden.
Trump has defended the July phone call with Zelensky, despite the rough transcript released by the White House appearing to support the allegations against him. Now they want to take their case for impeachment to the American public.
The comments from Graham come a day after House Republicans and Democrats sparred over whether the whistleblower would provide testimony as part of the impeachment inquiry, an aspect of the process that was seen as critical during the start of it, but was put to rest Saturday by House Intelligence Chairman Adam Schiff. Ron Johnson, R-Wis., said on CNN's "State of the Union".
"Let's focus on the problem, here", Mr Biden said.
