Kay Bailey Hutchison, R-Texas, will announce Wednesday that she will not retire and will stay in the Senate until her term ends in 2012."]Atlanta (CNN) – Sen. Kay Bailey Hutchison, R-Texas, will announce Wednesday that she will not retire and will stay in the Senate until her term ends in 2012, a Republican familiar with the announcement tells CNN.
"She is going to say she is staying through her term," said the GOP source, who spoke on the condition of anonymity, because the source was not authorized to speak on behalf of the senator.
Hutchison unsuccessfully sought the Republican Texas gubernatorial nomination, losing to Gov. Rick Perry earlier this month. National and Texas Republicans have urged Hutchison to stay in office, even though she pledged during the gubernatorial primary that she would leave the Senate.
Since losing the primary, Hutchison has been keeping a low profile and Texas Republican Chairwoman Cathie Adams said early Wednesday morning that she didn't even know what Hutchison planned to say.
"That is going to be very, very good news to a lot of people in people in Texas," Adams said. "The reason it is, is because of her seniority. People were reluctant about her running for governor because they did not want to lose her in Washington."
Texas Sen. John Cornyn, who oversees GOP Senate campaign efforts, and Senate Minority Leader Mitch McConnell of Kentucky will join Hutchison at the announcement.
Hutchison was first elected to the Senate in 1993, winning re-elections in 1994, 2000 and 2006.
