Washington (CNN) More than four months since the White House nominated Loretta Lynch to be attorney general, President Barack Obama is venting his frustration at a lack of progress and pushing for a confirmation.

"You don't hold attorney general nominees hostage for other issues. This is our top law enforcement office. Nobody denies that she's well-qualified, we need to go ahead and get her done," Obama told the Huffington Post. "The fact that she has now been lingering in this limbo for longer than the five previous attorney general nominees combined makes no sense."

Last Sunday, Senate Majority Leader Mitch McConnell told CNN he would not schedule a vote for Lynch until an otherwise bipartisan human trafficking bill -- stalled over an abortion provision opposed by most Democrats -- passes the chamber.

Democrats accuse Republicans of sneaking language into the human trafficking bill to prevent women from using restitution funds paid by perpetrators to get an abortion, although that provision was in the bill that passed the committee.

Until there's a vote on the trafficking bill, Lynch's nomination remains in limbo.
