Donald Trump to President Bush: You're fired!

The billionaire host of NBC's The Apprentice has weighed in on the Bush administration's decision to invade Iraq, terming it a "brutal mistake" that would "make it very hard for Bush to get re-elected".

Trump's numerous development projects have been crimped by the war.

"You can't get concrete. You can't get steel. You can't get anything in this country," he said.

"You know where all our steel's going? It's going to Iraq, because we're rebuilding Iraq."
