Lt. Gov. Mark Darr is announcing whether he'll seek the Republican nomination for a south Arkansas congressional seat.
Darr on Monday planned a campaign announcement in Huntington on Monday night.
Darr said last week he was likely to run for the 4th Congressional District now that Republican U.S. Rep. Tom Cotton is challenging Democratic Sen. Mark Pryor.
Darr was elected to the state's No. 2 constitutional office in 2010. Earlier this year, he ruled out running for governor and Senate.
House Majority Leader Bruce Westerman is expected to announce Tuesday in Hot Springs he'll run for the congressional seat.
Janis Percefull, a community college teacher from Hot Springs, is the only announced Democratic candidate for the seat.
