Ivanka Trump Mocked For Latest Excuse To Avoid New York Fraud Trial

Ivanka Trump apparently doesn’t want to testify in her family’s civil fraud trial and is taking extreme steps to avoid it.


Former President Donald Trump’s eldest daughter is scheduled to appear next week but asked a New York appeals court to pause the $250 million trial for reasons of “undue hardship,” according to CNBC.

The “undue hardship,” she claims, is being asked to testify “in the middle of a school week.”
New York Attorney General Letitia James called the request a “drastic” move that “would upend an ongoing trial.”

Currently, the former president and his sons Donald Trump Jr. and Eric Trump are co-defendants in the case, which alleges that the trio and others engaged in a long-running scam to falsely inflate the elder Trump’s net worth.
Although Ivanka Trump was originally a co-defendant as well, a New York appeals court removed her from the lawsuit earlier this year on statute-of-limitations grounds.
She worked at the Trump Organization as executive vice president for development and acquisitions until early January 2017, when she took a position in the White House as a senior adviser to her father.
