WASHINGTON (CNN) - Kansas Sen. Sam Brownback also addressed the summit – despite accounts from sources close to him indicating that Brownback is on the verge of ending his quest for the Republican presidential nomination.
Brownback spoke of the need to fight to outlaw abortion, and to defend the role of faith in America's political and public life.
He made no mention of his candidacy, or his plans to end it.
Several sources close to Brownback have said he planned to make an announcement as early as later Friday in his home state of Kansas.
