WASHINGTON (CNN) -- Police said on Thursday they have no reason to be suspicious of Ohio Rep. Paul Gillmor's death a day earlier.
Rep. Paul Gillmor was first elected to Congress in 1988.
Gillmor, a 68-year-old Republican, was found dead in his Arlington, Virginia, townhouse on Wednesday, police said.
"At this point, there is nothing that leads us to believe there is anything suspicious about Rep. Gillmor's death," Arlington Police Department spokesman John Lisle said.
"There are no signs of foul play, but we won't know the exact cause of death until the medical examiner makes that determination after the autopsy," Lisle said.
Gillmor, the deputy minority whip, was in his 10th term in the House and represented the 5th Congressional District in northwest Ohio..
House Minority Leader John Boehner, R-Ohio, told fellow representatives on the floor of the House that their colleague died "suddenly overnight."
A tribute to Gillmor was held in the House later Wednesday afternoon.
"Congressman Paul Gillmor's life was an extraordinary example to service and leadership," President Bush, attending the Asia-Pacific Economic Cooperation summit in Sydney, Australia, said in a statement.
"From working as an Air Force judge advocate during the Vietnam War to championing legislation in the halls of Congress, Paul devoted his career to strengthening his state and his nation," the statement said.
"He was a good man and dedicated public servant who represented the people of Ohio with distinction for four decades ... We will always remain grateful for his service."
Gillmor was a member of the House Committee on Financial Services, and the ranking Republican on the Subcommittee on Financial Institutions and Consumer Credit.
Gillmor also served on the Subcommittee on Capital Markets, Insurance and Government Sponsored-Enterprises and the Subcommittee on Housing and Community Opportunity.
He was elected to Congress in 1988, after serving in the Ohio State Senate for 22 years, where he was elected Republican leader five times.
Gillmor was born February 1, 1939, in Tiffin, Ohio. He received a bachelor of arts degree from Ohio Wesleyan University in Delaware, Ohio, and a law degree from the University of Michigan Law School.
In 2006, Roll Call -- a Capitol Hill newspaper -- listed him as the 43rd richest member of Congress, with an estimated net worth of $6.16 million. He formerly ran a financial services company.
Gillmor was also a U.S. Air Force veteran -- where he attained the rank of captain -- and served in the Vietnam War in 1965 and 1966.
He ran unsuccessfully for governor in 1986.
He was married to Karen Gillmor, vice chairman of the State Employment Relations Board in Ohio and a former state senator.
Their family includes two daughters, Linda and Julie, and three sons, Paul and twins Connor and Adam. E-mail to a friend
