WASHINGTON — Sen. Tim Johnson, chairman of the Senate Banking Committee, has said he will announce a decision about whether to run for office again in 2014 sometime next week.

Johnson said last week that he hadn't yet made up his mind about running, according to the Rapid City Journal. Observers have speculated that Johnson's retirement could pave the way for his son Brendan Johnson, South Dakota's U.S. attorney, to run for the seat.

The South Dakota Democrat, who suffered a stroke in 2006, would be running for a fourth term. He's served as chairman of the banking panel since 2011, staunchly defending the Dodd-Frank reform law named after his predecessor Sen. Chris Dodd, D-Conn. Next in line for the banking chairmanship is Sen. Jack Reed, D-R.I.

A spokesman for the Banking Committee declined to comment until Johnson's decision is made public.
