The White House’s gun-centered campaign will begin in earnest on Friday, with Biden traveling to Richmond with Sen. Timothy M. Kaine (D-Va.) and several Cabinet secretaries to hold a roundtable session focused in part on the 2007 mass shooting at Virginia Tech.

Obama, meanwhile, will hit the road soon and is expected to make an emotional appeal in his State of the Union address, scheduled for Feb. 12. The White House is considering inviting families of the children who died in last month’s school shooting in Newtown, Conn., to join first lady Michelle Obama in her viewing box, said a Democratic source close to the White House.
