Republican Sen. Brownback enters presidential race

Republican Sen. Sam Brownback of Kansas, a favorite of religious and social conservatives, formally announced his bid for the White House on Saturday, pledging to keep God in the government.

Brownback, a two-term Senate veteran and staunch opponent of abortion and same-sex marriage, told a cheering crowd of about 800 supporters that he would seek the Republican nomination for the presidency for 2008 because he wanted to renew "the family and the culture."
