WASHINGTON (AP) — A watchdog group is asking the Justice Department to investigate whether President Donald Trump’s daughter Ivanka violated federal conflict-of-interest law by her key role in promoting an Opportunity Zone tax break program from which she could potentially benefit.

The complaint from the Citizens for Responsibility and Ethics in Washington follows an Associated Press investigation last month. The AP found that, as White House aides, Trump and her husband Jared Kushner both backed the Opportunity Zones program, which could financially benefit the couple.

Kushner owns a $25 million to $50 million stake in Cadre, a real estate platform has announced plans to invest in several cities under the Opportunity Zones program.

The CREW complaint says that, under the law, Kushner’s financial interests are considered of value to Ivanka Trump.
