In Washington, the announcement was expected but the name was not.
Harriet Miers, age 60, has never been a judge nor argued a case at the Supreme Court.
She is a soft-spoken attorney from Dallas who was Mr. Bush's lawyer in Texas and has often spent time with him at his ranch.
"I am very grateful for the confidence in me that you've shown by this nomination and certainly I am humbled by it," said Miers after the nomination to the Supreme Court was announced.
Some legal experts say she has much to be humble about.
Miers was a math major at Southern Methodist University and stayed there for law school.
In 1972, she was the first woman ever hired by the Dallas firm Locke Purnell.
In the 1980s, Miers became president of the Dallas bar and served on the city council. As a Texas democrat at the time, she gave a thousand dollars to moderate Senator Lloyd Bentsen's re-election campaign and Al Gore's first presidential campaign when he tried to run as a centrist.
In the mid 1990s, Texas Governor Bush hired Miers in a private property dispute. In 1995, he named her to the Texas lottery commission. The commission was in the midst of a scandal, and Miers became a driving force in the cleanup.
It was one reason Governor Bush introduced her at an event the next year as a, "Pit bull in size 6 shoes."
In 1998, the Bush gubernatorial re-election campaign paid Miers $19,000 to examine rumors questioning Bush's service in the National Guard.
Miers then became deeply involved in the 2000 presidential campaign and the Florida recount.
At the White House, she has served as White House Secretary, Deputy Chief of Staff, and White House Counsel, answering questions from the public online and blending into the crowd last week at John Robert's swearing in.
Miers is a devout church-goer who has never been married.
A few years ago, she was named one of the 50 most influential women lawyers in America.
While her constitutional views are unknown, colleagues point to an issue 10 years ago at the American Bar Association. Miers repeatedly tried to get the organization to vote on its pro-choice positions.
President Bush reassured conservatives by saying, "Harriet Miers will strictly interpret our Constitution and our laws. She will not legislate from the bench."
But because Miers has never proven herself on the bench, some on the right are calling the nomination "bitterly disappointing."
Former Bush speech writer David Frum wrote, "The Miers nomination is an unforced error...it is simply reckless for any conservative president, especially one backed by a 55-seat Senate majority, to take a hazard on anything other than a known quantity."
As for Miers, in addition to a blank slate on the issues, she is said to be tightly wound and anxious about public speaking. That could make her confirmation hearings even more unpredictable.
