It remains unclear exactly how many and who of the uncommitted Democratic superdelegates in the Senate will be in attendance at the meeting, which is being held at the Democratic Senatorial Campaign Committee headquarters near the Capitol.
CNN spotted Sens. Tom Harkin of Iowa, Ken Salazar of Colorado, and Tom Carper of Delaware head into the meeting.
In a brief interview with CNN, Harkin said the point of the meeting is "to discuss what if anything we might do after the polls close tomorrow night together."
An aide to a senator in the meeting tells CNN's Gloria Borger that it’s “not likely” anyone will come out today with an endorsement. “It’s a how-do-we-do-what we-want-to-do” meeting," the aide said.
"Some want, after the primaries are over, to come out in a group; others feel the need to do it with state delegations. The Obama campaign wants a group of senators to come out together, for obvious reasons.”
The aide said it's “more likely,” the endorsements will come at the end of the week, but added, "anything is possible after Tuesday.”
