Sen. Ron Johnson (R-WI) is sending mixed signals regarding a 2028 run for reelection.

Johnson, who was sent into office in 2010 as part of the Tea Party surge, spent much of his appearance at a Milwaukee Press Club event bemoaning his role as senator, saying he didn’t “covet” the position, the Hill reported. He then raised eyebrows when he commented on the 2028 election for his senate seat, leaving it uncertain whether or not he would run.
