Donald Trump, the presumptive Republican presidential nominee, was in Washington on Thursday as part of a closed-door deposition in a $10 million breach-of-contract lawsuit he filed against famed chef Geoffrey Zakarian.

Trump gave a thumbs-up from inside a black town car just before 10 a.m. as it pulled into a garage near the law offices of Pillsbury Winthrop Shaw Pittman in the 1200 block of 17th Street NW.

Trump’s lawsuit was filed in D.C. Superior Court.

Zakarian is represented by Deborah B. Baum, a lawyer with the firm.

Outside the building, protesters held up yellow “Dump Trump” signs. And dozens of other protesters at the headquarters of the Human Rights Campaign, which sits across the street, joined the Trump protesters and held signs that read, “Love Conquers Hate.”

Trump sued Zakarian after the chef terminated plans to open a restaurant in Trump’s new Washington hotel, the $200 million makeover of the Old Post Office Pavilion on Pennsylvania Avenue, after Trump launched his campaign by denouncing Mexican immigrants as drug dealers and rapists.

Separately, Trump also filed a lawsuit against renowned chef José Andrés, who also terminated his restaurant plans following Trump’s statements.

On Thursday, Trump and his entourage left the Pillsbury law offices after nearly 2 1/2 hours. About 100 protesters were outside and chanted “Love conquers hate.”

Workers in nearby buildings crowded against windows looking down onto Rhode Island Avenue. Trump’s convoy of cars with New Jersey license plates headed down an alley, going west.

Meanwhile, according to court records, D.C. Superior Court Judge Brian Holeman extended the discovery period in the lawsuit through July 29 to allow attorneys to depose other witnesses.

On Wednesday, attorneys for Trump and Andrés argued their sides in the case in D.C. Superior Court. Neither Trump nor Andrés was present at that hearing.
