John Diehl, the expected speaker of the Missouri House if he wins reelection next month, has changed law firms.

Diehl, who had been a partner at Armstrong Teasedale in St. Louis, is now listed as partner at Husch Blackwell, also of St. Louis. The firm lists Diehl as partner in real estate, development and construction.

Diehl, R-Town and Country, is the House Majority Leader. He was informally tapped to be speaker earlier this year. The House will formally vote on a speaker after the Nov. 4 election. Diehl faces a challenge from Democrat Al Gerber.
