Trump to testify in trial focusing on dealings with investors in namesake Chicago skyscraper

CHICAGO - Donald Trump is known for grilling contestants on his TV show, "Celebrity Apprentice." But he'll be in the hot seat Tuesday as he takes the stand at a civil trial in Chicago.

Several of Trump's companies are named in a lawsuit filed by an 87-year-old investor who says she was lured into buying condos at his namesake Chicago skyscraper with promises of a profit-sharing deal that were later quietly withdrawn.

Jacqueline Goldberg bought two condos for around $1 million apiece at the Trump International Hotel

Trump's lawyer says Goldberg signed documents giving Trump executives the power to cancel the profit-sharing offer.
