Federal Agents Raid State Sen. Robert Mellow's Office and Home
Agents executed search warrants at the home and district office of a top Pennsylvania state senator as part of a federal investigation into allegations of illegal activity, an FBI official said Friday.

The search stems from a joint FBI- IRS investigation into Sen.

Robert J. Mellow, FBI spokesman Frank Burton Jr. said.

A spokeswoman for Mellow, the Senate Democratic leader from

Lackawanna County, said the office were not aware of an investigation before being informed Friday morning prior to agents' arrival.

"Sen. Mellow is confident that in his 40 years serving northeastern Pennsylvania he's done nothing wrong," spokeswoman Lisa Scullin said.

Mellow is cooperating fully with all requests, she said.

"He's willing to provide any information that's deemed necessary in completing their inquiry," she said.

Neither Burton nor Scullin would discuss the nature of the allegations, say what the agents were seeking or say what they took, if anything, from the Scranton-area properties.

IRS agents were among the investigators at Mellow's home and office, IRS spokeswoman Shauna Frye said. She said she could not comment beyond that.

Mellow, in his 10th term, is the state Senate's longest-serving member and has been the Democrats' floor leader for much of the past two decades. In February, he announced he would retire at the end of this year because he wants to spend more time with his daughters and grandchildren.

He was first elected to the Senate in 1970 and served for about 16 months in the early 1990s as the Senate's president pro tempore.
