The suspensions of Senators Patrick Brazeau, Mike Duffy and Pamela Wallin are likely to be addressed by NDP Leader Tom Mulcair following the party's caucus this morning.
Mulcair will speak to reporters at 11 a.m. ET. CBC News will carry it live.
The Senate voted Tuesday night to suspend Brazeau, Duffy and Wallin with benefits. They won't be paid, or have access to office space or staff. The suspensions last as long as the current session of Parliament.
All three are under investigation by the RCMP over questionable expense claims. No one has beencharged.
