(CNN) Joe Biden's campaign announced Thursday the co-chairs of its vice presidential selection committee who will lead the charge to vet potential running mates.

Former Sen. Christopher Dodd of Connecticut, Congresswoman Lisa Blunt Rochester of Delaware, Los Angeles Mayor Eric Garcetti and Cynthia C. Hogan, a former White House and Senate counsel to Biden, will chair the committee's search for the right woman to join Biden on the Democratic ticket. The former vice president told donors during a fundraiser Wednesday that he hopes this vetting process will be done by July.

Biden has promised to choose a woman as his running mate and said he will pick someone who is "simpatico" with his views. He also recently shared that former President Barack Obama had advised him to pick someone who "has strengths where I have weaknesses."

"Selecting a vice presidential candidate is one of the most important decisions in a presidential campaign and no one knows this more than Joe Biden," Biden campaign manager Jen O'Malley Dillon said in a statement.

"These four co-chairs reflect the strength and diversity of our party, and will provide tremendous insight and expertise to what will be a rigorous selection and vetting process. We are grateful for their service to the campaign and for their leadership."
