(CNN) — Rick Santorum has invited former aides to Washington next week for a "private briefing" on his plans for a possible 2016 presidential bid.
The "Personal Invitation from Senator Santorum," provided to CNN by a Republican who received it, was sent by a Santorum aide to more than two dozen "friends and former colleagues" from past campaigns and his time in the U.S. House and Senate.
"As you probably know, RJS is seriously considering a run for the White House in 2016," Santorum adviser Matt Beynon wrote in the email, using Santorum's initials.
"With the midterms and the new year behind us, he is beginning the final stages of preparation and consideration of another campaign," Beynon wrote.
