ABC News' Jake Tapper Reports: Sources close to Senator Hillary Clinton's presidential campaign tells ABC News that former astronaut Sen. John Glenn, D-Ohio, will endorse Sen. Hillary Clinton, D-NY, tomorrow in Columbus, Ohio, at 1 pm local time.
Glenn will appear at the endorsement event with Gov. Ted Strickland, D-Ohio, another prominent Clinton-backer in the must-win state, which will hold its primary in three weeks.
Clinton will not be there.
Glenn ran for president in 1984.
In the presidential arena, at least, he did not have the right stuff.
