Nearly six months after he pled guilty to receiving hidden payments for endorsing Ron Paul, former State Senator Kent Sorenson still hasn’t been sentenced and won’t be for some time. Jason Noble reported for the Des Moines Register,

In a [February 19] hearing before U.S. District Judge Robert W. Pratt, attorneys for the government and for Sorenson agreed to delay sentencing in the case until April. The reason, Justice Department lead attorney Robert Higdon Jr. said, was that the government was “engaged” and “making progress” on a “larger investigation” into the 2012 presidential race. […]

It is unclear exactly who may be the target of the ongoing investigation, but questions have been raised about top aides in Paul’s 2012 campaign.

Sorenson received shady indirect payments from Michele Bachmann’s presidential campaign for months, but his guilty plea was related to a payment scheme he negotiated with Ron Paul supporters. Russ Choma reported last year for the Open Secrets blog,

Sources say two grand juries are looking into the 2012 campaigns of Rep. Michele Bachmann (R-Minn.), whom Sorenson originally endorsed, and Paul, to whom Sorenson switched his support just days before the Iowa caucuses. A number of individuals confirmed to OpenSecrets Blog that they had been interviewed by FBI agents, the grand juries, or both.
