"I think he's a very fine appointment. Chris Cox is respected throughout the House. He's knowledgeable, he's serious, he has a cool head that prevails over and over and over again. I think the president has nominated someone who will serve very well at the SEC."Bush called Cox "a champion of the free enterprise system" during a White House ceremony. Cox won election to the House in 1988, after a stint as a White House counsel during the Reagan administration. He rose to the GOP leadership after Republicans won the majority in 1994, and made a fleeting one-day run at the speakership during a leadership upheaval that led to the ascension of Speaker Dennis Hastert. Cox has steadfastly pursued elimination of the corporate dividend tax and capital gains tax, which were reduced under Bush, and ending the estate tax. Cox will be the SEC's third chairman under Bush, after Donaldson and the controversial Harvey Pitt, who stepped down after a series of embarrassing political missteps.
