JEFFERSON CITY -- GOP auditor candidate Thomas Scweich flexed a little muscle of his own today after opponent Allen Icet announced the endorsement of Kenny Hulshof.

Schweich, who early on was endorsed by several key Missouri Republican leaders, announced that one of the biggest names backing him, former attorney general and senator, John Ashcroft, will be a featured voice on robo-calls going to voters starting tonight.

Former U.S. ambassador to the United Nations John Bolton has also recorded phone messages supporting Schweich.
