UPDATED 10:40 p.m. NORMAL - U.S. Sen. Roland Burris, now the target of an investigation into possible perjury, said he welcomes inquiries into his testimony at former Gov. Rod Blagojevich's impeachment hearings. | Lawmakers: Burris should have come clean | Video

"I support having any other body or agency look into my testimony as it was truthful and consistent," Burris said, reading a prepared statement during a stop Tuesday evening at Illinois State University as part of a tour of the Twin Cities.

The statement came on the same day as reports that indicated a U.S. Senate ethics committee inquiry has begun and the Sangamon County state's attorney is looking into the matter.

"I welcome the opportunity to go before any and all investigative bodies, including those referred by Illinois Attorney General Lisa Madigan and the Senate ethics committee to answer any questions they have," Burris said in his statement.

Burris said his staff is preparing a "concise document" to be released soon, which will answer all questions on the matter.

Burris was in Bloomington-Normal Tuesday as part of his first tour of the state since being appointed by Blagojevich to the Senate seat once held by President Barack Obama. At each stop he avoided answering reporters' questions, including physically brushing past them at times.

Sangamon County State's Attorney John Schmidt acknowledged Tuesday he is reviewing documents from Illinois House Speaker Michael Madigan's office regarding Burris' testimony to the Illinois House impeachment panel.

In an affidavit that came to light last week, Burris supplemented his Jan. 8 testimony to the impeachment panel.

The affidavit included bombshell revelations that he had talked with the former governor's brother, Rob Blagojevich, about the Senate appointment and whether he could raise money for the governor. Burris said Monday that in the end, he raised no money and hosted no fundraiser.

Burris, a 71-year-old Chicago Democrat, did not mention that and other conversations in his testimony to the committee.

The impeachment effort came soon after Rod Blagojevich was arrested in December on federal corruption charges alleging he was trying to sell the Senate seat,

Lisa Madigan, who is the speaker's daughter, issued a statement Tuesday saying Schmidt's office is the proper venue for the case to be investigated.

Schmidt did not offer a timeline for the review, which fell under his jurisdiction because the impeachment committee was meeting in the Sangamon County seat of Springfield.

During his visit to Bloomington-Normal on Tuesday, Burris, a member of the Senate's homeland security committee, met with State Farm Insurance Cos. emergency response team.

His subsequent visit to ISU included a closed-door meeting with ISU President Al Bowman. He said they discussed higher education, the inner workings of the U.S. Senate and the federal stimulus package, but not the controversy.

"I've been reading about it all day. I decided to let him bring it up," said Bowman, who said he's known the senator about 20 years. Bowman described Burris' mood as congenial, adding he was "the same Roland Burris I've always known."
