During a debate Monday, Democratic Massachusetts U.S. Senate candidate Elizabeth Warren cited Republican Sen. Richard Lugar as an example of a someone she could work with on a bipartisan basis.

On Tuesday, Lugar — who will no longer be in office next year when a victorious Warren could take office, endorsed Warren’s opponent Sen. Scott Brown.

In the endorsement, Lugar praised Brown as a senator committed to reaching out to Democrats.

“My friend, Scott Brown, since becoming a United States Senator has worked hard to reach across the aisle, Lugar said. “In just two and a half years, he has established himself as a Senate leader who can be counted upon to rise above partisanship and do the right thing.”

“As an example, in order to confirm the START nuclear arms control treaty with Russia, Scott approached the issue with an open mind and announced his support for the Treaty at a critical moment, leading the way toward bipartisan ratification,” Lugar added.

“We need Senators like Scott Brown in the U.S. Senate, and I wholeheartedly endorse him.”
