Joe Biden has hired Covington & Burling to provide legal counsel to his presidential campaign, turning to a law firm stocked with prominent veterans of the Obama administration, including former U.S. Attorney General Eric Holder.

Leading the firm’s work for the former vice president is Robert Lenhard, a former chairman of the Federal Election Commission who joined Covington as a partner in 2008. That year, as Barack Obama and Biden prepared to enter the White House, Lenhard oversaw the transition team that reviewed the FEC for their incoming Democratic administration.
