Leading Democrat presidential contender Joe Biden waffled on impeaching President Trump in a campaign statement issued in response to Special Counsel Robert Mueller’s remarks at the Justice Department Wednesday morning about his investigation into President Trump and Russian influence operations on the 2016 election.

While other Democrat rivals called for impeachment Wednesday, the former Obama vice president played it both ways–not calling for impeachment but calling on Congress to continue investigations into Trump that could lead to impeachment.

The close of Biden’s statement waffles on impeachment, “Vice President Biden agrees with Speaker Pelosi that no one would relish what would certainly be a divisive impeachment process, but that it may be unavoidable if this Administration continues on its path. For all these reasons and many more, Vice President Biden will continue to make the case as to why President Trump should not be re-elected. That is the surefire way to get him out of office.”

Biden’s rivals did not waffle.

Sen. Elizabeth Warren (D-MA):

Mueller’s statement makes clear what those who have read his report know: It is an impeachment referral, and it’s up to Congress to act. They should. — Elizabeth Warren (@ewarren) May 29, 2019

Sen. Kamala Harris (D-CA):

What Robert Mueller basically did was return an impeachment referral. Now it is up to Congress to hold this president accountable. We need to start impeachment proceedings. It's our constitutional obligation. — Kamala Harris (@KamalaHarris) May 29, 2019

South Bend, Indiana Mayor Pete Buttigieg:

This is as close to an impeachment referral as it gets. Robert Mueller could not clear the president, nor could he charge him — so he has handed the matter to Congress, which alone can act to deliver due process and accountability. — Pete Buttigieg (@PeteButtigieg) May 29, 2019

Sen. Cory Booker (D-NJ):

Robert Mueller’s statement makes it clear: Congress has a legal and moral obligation to begin impeachment proceedings immediately. — Cory Booker (@CoryBooker) May 29, 2019

Biden leads the Democrat field with 38 percent support, trailed by Sen. Bernie Sanders (VT) at 20 percent and all others in single digits, according to a Morning Consult poll released Tuesday.
