One person who isn't a fan of his tweets: his wife, Barbara.

Barbara Grassley told the Iowa Gazette that she doesn't tweet or use text messaging — yet. She doesn't always appreciate her husband's prolific tweeting either, especially when he pulls out his phone in church.

"I had had to tell him to knock it off," she said, reportedly making a motion as if slapping the senator’s hand. "Put it away."

Sen. Grassley is famous for tweeting an episode in April where he accidentally set his pants on fire: "Work on farm Fri. Burning piles of brush WindyFire got out of control. Thank God for good naber He help get undr control PantsBurnLegWound."

Mrs. Grassley admitted she has little control over her husband's tweeting, or whether he chooses to again run for reelection. Chuck Grassley has served five terms since winning election to the Senate in 1981.

"I thought the last one was. I guess that shows what I know," Barbara Grassley said.

"I suppose I could have something to say about that if I wanted to say it," she added.

The senator's latest tweet this weekend? "Finishing busy week-15 official events in every corner of Iowa"
