Donald Trump testified he paid a contractor more than $3 million for work that was only half-done on his Briarcliff Manor, N.Y., golf course.

"This is very simple case: I had a contractor that didn't perform," Trump told "Celebrity Justice" about his Monday testimony against Columbus Construction Corp. of Mount Vernon, N.Y.

Trump's suit claims he paid more than $3 million to the construction company by August 2001 when less than half of the work on the Trump National Golf Club was complete.

Trump, who readily fires people on NBC's "The Apprentice," said he did not fire Columbus Construction because he thought it would be more difficult to hire another contractor to finish the golf course.
