DALLAS (AP) -- Dallas Mayor Tom Leppert is not seeking a second term amid speculation he plans to run for U.S. Senate.
Leppert early Monday made the announcement in a news release, plus e-mailed thousands of supporters.
Leppert's statement did not mention whether he plans to seek the seat held by GOP Sen. Kay Bailey Hutchison, who last week announced she will not run for re-election in 2012.
Republican Leppert says his accomplishments include adding almost 600 officers to the Dallas police force, building a strong economy and "shining a light on education" to ensure future success.
Leppert says, in the next few weeks, he plans to lay out how he can best serve the people of Dallas, North Texas and the entire state.
