LEADING THE DAY: Facebook has hired former Clinton White House press secretary Joe Lockhart as its vice president of global communications, The Washington Post reported. Lockhart will be based at Facebook’s Silicon Valley headquarters. (Washington Post Co. chairman Donald E. Graham sits on Facebook’s board of directors.)

Lockhart’s D.C. counterpart, Marne Levine, was chief of staff to former White House National Economic Council director Lawrence Summers, and the company also recently hired Joel Kaplan, former George W. Bush deputy chief of staff, to head its D.C. lobbying office.
