One of the ethics complaints claims Kavanaugh lied about the sexual assault allegation against him, Buzzfeed News reported. He was sworn in on Saturday by Chief Justice John Roberts and former associate justice Anthony Kennedy, for whom he clerked 25 years ago.
Tymkovich, the judge who is now in charge of investigating the complaints, was appointed to the bench by President George W. Bush and was on President Donald Trump's list of possible Supreme Court nominess, though Trump ultimately chose Kavanaugh.
It is unclear what will come of the review by the 10th Circuit.
"There is nothing that a judicial council could do at this point", said Arthur Hellman, a law professor at the University of Pittsburgh and expert on the operation of federal courts.
Merrick Garland, the chief judge of the D.C. Circuit, typically deals with ethics complaints, but he apparently stepped aside from complaints against Kavanaugh. "Folks who feel very strongly one way or the other about the issues in front of us should get out and vote and participate".
The Kavanaugh confirmation has blown open the midterm elections from being a national referendum on Trump's stewardship to a raw emotional discussion over the lack of women in power and how to handle sexual misconduct allegations.
"This was just basically sending as strong a signal as we could as candidates to the members who are now in to say that we need to take on these issues upon the new Congress coming in", Ms. Slotkin said.
He has now appointed Neil Gorsuch and Brett Kavanaugh which has swung the court 5-4 in the Republicans' favour, meaning abortion rights are once more in the balance. Details of the complaints have not been made public.
The existence of misconduct complaints and the procedure can be disclosed, according to the rules, "when necessary or appropriate to maintain public confidence in the judiciary's ability to redress misconduct or disability".
