Stay tuned to Kay's Radio Iowa blog for the blowbyblow.
Update: Seems like early indications were wrong. Congressman King in fact endorsed Fred Thompson. Kay has the details.
Update 2: Thompson's out with a statement.
"Congressman King's leadership in support of the sanctity of life and his efforts in the fight against illegal immigration have made him one of Iowa's great Republican leaders. He's a tireless fighter for the 5th district of Iowa and I'm honored by his support. I look forward to working with Congressman King over the next three weeks and into 2008 in support of the traditional conservative values he and I share."
