Restaurants and hotels in which President Donald Trump has financial interests are unfairly siphoning business away from competitors in New York and Washington, D.C., the new plaintiffs in a watchdog group's emoluments suit against Trump allege.

The new plaintiffs may help Citizens for Responsibility and Ethics in Washington (CREW), which filed an amended complaint on Tuesday adding Restaurant Opportunities Centers United and a woman who books embassy events for two Washington hotels, bolster its case for standing in the suit.

Deepak Gupta of Gupta Wessler, a member of CREW's legal team, said the new plaintiffs make the plaintiffs' standing in the case “irrefutable.”
