According to GovExec, that position could change hands after the election as industry observers and congressional sources told the publication Tom Carper (D-Del.) is a likely successor.
McCaskill is in the midst of a close reelection campaign in Missouri and even if she does win, those sources believe she may decide to focus on her more-permanent assignment chairing the Armed Services Readiness and Management Support Subcommittee.
Carper would likely give up his chairmanship of the Financial Management subcommittee, according to the report.
Alan Chvotkin, executive vice president and counsel of the Professional Services Council, told GovExec Senate rules limit the total number of subcommittees as the caucuses vote on membership.
