Retiring Sen. Evan Bayh (D-Ind.) escorted President Obama off Air Force One after it landed at an Indiana Air Force base Tuesday.
The president is in Indiana, a state he won for Democrats for the first time since 1964, to tour a Chrysler auto plant and deliver a speech on the economy.
Bayh, who declined to seek reelection this year, has sometimes clashed with the White House over legislative priorities such as healthcare reform and cap-and-trade climate legislation.
The senator last month praised a campaign ad that that depicted now-Sen. Joe Manchin (D-W.Va.) shooting what was supposed to be a copy of the cap-and-trade bill with a rifle, a move that angered Democratic leaders. He also said that the Democrats' big legislative achievements were not helping members at the polls.
The day before Election Day, Bayh also said that sweeping Republican wins in the midterm elections could help Obama win a second term in 2012.
