CHICAGO (CBS) — As deposed governor Rod Blagojevich serves his 14-year sentence on convictions that included trying to sell a U.S. Senate seat, his brother is headed to Washington to talk about who he claims offered to buy it.

As WBBM Newsradio’s Dave Berner reports, the House Committee on Ethics is investigating U.S. Rep. Jesse Jackson Jr. (D-Ill.), and is expected to interview Robert Blagojevich later this month.

The Chicago Sun-Times reports the panel is taking Robert Blagojevich up on the late offer he made last year to provide details about being approached with a pay-to-play scheme for President Barack Obama’s vacant Senate seat.

The former governor’s brother says some of what he has to say has never been made public, the Sun-Times reported.

Robert Blagojevich said he personally wrote to 10 members of the Ethics Committee, and now those congressmen are ready to hear what he’ll be saying, the newspaper reported.

Robert Blagojevich was charged along with his brother, and was tried along with Rod Blagojevich at his first trial in 2010. But jurors deadlocked on all the charges against Robert Blagojevich and prosecutors dropped the charges against him soon after.

Rod Blagojevich was convicted of 18 counts of corruption last year and was sentenced to 14 years in prison, which he began serving last month.
