Governor Mark Dayton is expected to announce his appointment to Al Franken's Senate seat Wednesday morning.
According to Minnesota Public Radio, which cited an unnamed source with first-hand knowledge, Minnesota's Lt. Gov. Tina Smith will replace Franken.
That source also told MPR that Smith plans to run for the seat in next year's special election.
She began serving back in January of 2015. The official announcement is expected at 10 a.m.
Franken announced he would be resigning from his seat last week after multiple allegations of sexual misconduct.
The resignation adds another big race to what was an already busy ballot in Minnesota next November.
Governor Dayton is appointing someone to Senator Franken's seat until a special election can be held next November.
This election coincides with the general election during which several big seats will be on the ballot including Minnesota governor.
The open seat for governor's office has already attracted more than a dozen candidates in both parties.
The unexpected resignation of Senator Franken has put both of Minnesota's U.S. Senate seats on the ballot next fall including the seat of Senator Amy Klobuchar.
All of Minnesota's executive officers are up for election as well as all the seats in the Minnesota House of Representatives, and all of Minnesota's eight seats in the United States House of Representatives.
UMD Political Science professor Cindy Rugeley says it will be an important election to watch
Rugeley says, "the legislature that we elect will be doing redistricting for the next decade. It's a very very important election and I think it's very important to both parties and it's going to be interesting to watch."
Currently, there is an online petition circling asking Senator Franken to keep his seat. That petition currently has over 19,000 signatures out of a goal of 25,000.
Meanwhile, 32 democratic and one Republican senators called on Franken to resign in the days prior to his announcement as more sexual misconduct allegations surfaced.
Governor Dayton will make the announcement at the Capitol Wednesday morning at ten.
We will be streaming the announcement live on air and online starting at 10 a.m.
