(Charleston-AP) Aug. 25, 2003 - Former Attorney General Charlie Condon says America's greatest challenge is winning the war on terrorism and it will take changes in national policy to it.

Condon announced his candidacy for the US Senate in a formal speech at The Citadel on Tuesday. Condon said he would work to ensure that law enforcement, intelligence and immigration databases are better integrated, to tighten policies on visitor visas and to push for development of drugs to treat people injured in biological attacks.

Condon is seeking the Republican nomination for the seat held by Democratic US Senator Ernest "Fritz" Hollings. Hollings is retiring in 2004 after more than three decades in Washington.

At least three other Republicans are seeking the GOP nomination: Congressman Jim DeMint of Greenville, Myrtle Beach Mayor Mark McBride and Lowcountry real estate developer Thomas Ravenel.

Democrats seeking Hollings' seat include Columbia Mayor Bob Coble, state Education Superintendent Inez Tenenbaum and Camden native Marcus Belk.
