Tennessee Sen. Brian Kelsey to change federal plea

Why it matters: The change suggests the case could come to a close soon, capping a precipitous fall for Kelsey (R-Germantown), who had been a rising star in state politics before his indictment last year.

• Kelsey's co-defendant, Josh Smith, reached an agreement with prosecutors and pleaded guilty to a charge in the case earlier this month.

The details: Prosecutors accused Kelsey and Smith of working with unnamed, unindicted co-conspirators, political groups and others to illegally funnel more than $106,000 from Kelsey's state campaign coffers to support his federal race in 2016.

• Kelsey forcefully denied the allegations when he was indicted, calling the case a "witch hunt." His lawyers did not respond to questions about the plea change.

The intrigue: Kelsey is still a state lawmaker, but not for long.

• He did not run for re-election, and his successor will be selected in the Nov. 8 election.
