Washington ? One of the Senate’s senior conservatives, Republican Orrin Hatch, offered unconditional support Tuesday to Supreme Court nominee Harriet Miers amid expressions of anxiety in some Republican quarters over her legal philosophy.

The Utah Republican took on criticism that Miers has no experience as a judge and a largely unknown track record – something that worries some conservatives.

“A lot of my fellow conservatives are concerned, but they don’t know her as I do,” said Hatch, a former Judiciary Committee chairman. “She’s going to basically do what the president thinks she should, and that is be a strict constructionist.”

Hatch said he already has decided to support her. “I don’t need any more. I know her really well. And I intend to support her,” he told reporters.

President Bush, at a news conference in the White House’s Rose Garden, asked the Senate to confirm Miers by Thanksgiving and urged Democrats to give her a chance to explain her views.

Miers, who was meeting Tuesday with Finance Committee Chairman Charles Grassley, R-Iowa., and Judiciary Committee member Jeff Sessions, R-Ala., was nominated to replace Justice Sandra Day O’Connor.

Some conservatives aren’t confident in Miers yet.

“I have said in the past that I would like a nominee with a proven track record on important issues to all Americans and whose judicial philosophy is well-formed,” said Sen. Sam Brownback, R-Kan. “I am not yet confident that Ms. Miers has a proven track record.”
