- He was an active member of the Mormon church
Bennett was 82 years old.
"His final days were filled with kindness and love, and the family greatly appreciates the outpouring of well wishes and support," the statement said. "It touched his heart, and deeply touched ours, to see how much he was loved."
Bennett served as a senator from Utah for 18 years. His father, Wallace Bennett, also served in the Senate.
Current Senate Majority Leader Mitch McConnell praised Bennett's work ethic in a statement Wednesday.
"Bob preferred the often low-key work of legislating to the bright lights of the media," McConnell said.
On Thursday, President Barack Obama said in a statement that he and first lady Michelle Obama were saddened to learn of Bennett's passing.
"His commitment to his constituents transcended partisanship and he often reached across the aisle to get things done," Obama said. "He was a dedicated public servant and his work -- like efforts to save the country from economic collapse -- is exemplary of what we can accomplish when we put aside our differences and focus on our common goals."
First elected to the Senate in 1992, Bennett served as a senior member of the Senate Appropriations Committee, the Senate Banking Committee, the Senate Committee on Rules and Administration and the Joint Economic Committee. He was known as a conservative who was willing to compromise and find common ground with his colleagues across the aisle.
