Authorities say a plane carrying Senate minority leader Trent Lott to a campaign event in Missouri landed in Alabama after pilots reported problems with the landing gear.
The plane took off from Lott's hometown of Pascagoula, Mississippi.
Lott's spokesman Lee Youngblood says it was rerouted to Alabama after a landing gear light malfunction.
Youngblood says the landing gear would not retract, so pilots decided to "land and find out what the problem was rather than risk it.''
Republican Senators Peter Fitzgerald of Illinois and Rick Santorum of Pennsylvania, also had been scheduled for the flight but changed their plans, their offices said Tuesday.
The incident happened three days after Minnesota Sen. Paul Wellstone was killed in a plane crash in Minnesota, along with his wife, their adult daughter, three campaign staffers and two pilots.
