Sen. Tim Johnson will announce his future plans Tuesday afternoon in his home town of Vermillion.

Johnson, 66, is widely expected to announce he will retire in 2014 after three terms in the U.S. Senate.

Citing anonymous sources, Reuters reported Monday afternoon that Johnson will not seek a fourth term in the Senate.

A Johnson spokesman declined to comment on the Reuters report.

“I’m not responsible for what Reuters puts out,” said Perry Plumart, Johnson’s director of communications.

Plumart said he couldn’t provide any details about the Tuesday speech beyond the time and location.

Johnson’s Vermillion announcement will be at 3 p.m. at the Al Neuharth Media Center on the University of South Dakota campus. The event is open to the public.

Argus Leader Media will livestream Johnson’s remarks at argusleader.com.
