State Sen. John Lehman said his campaign wasn't responsible for a tweet that called a Republican constituent a "moronic fool."
Lehman said neither he nor his staff posted Thursday's tweet. The Racine Democrat said his campaign's Twitter account had a simple password, and he believes a "mischief-maker" was able to hack it.
The tweet was directed to Republican blogger Tamra Varebrook of Union Grove.
It read: "@TamraTellsIt "Rookie Blogger" is that how we say moronic fool nowadays? #wiright #p2."
Varebrook ran as a fake Democrat against Lehman in May to force a Democratic primary ahead of an election to recall then-state Sen. Van Wanggaard.
The 43-year-old homemaker says she was "completely shocked" by the tweet.
A Journal Times of Racine report said Lehman is deactivating the Twitter account.
