A group of Uber drivers started a petition on Thursday calling on the company’s CEO to step down from President Trump’s advisory committee — and to make promises that it will protect any worker threatened with detainment or deportation.

The petition started by the Independent Drivers Guild demands that Uber chief executive officer Travis Kalanick quit Trump’s council. It also demands that the company give money to groups fighting the so-called Muslim ban and state publicly that drivers will not be penalized for acting in protest of the ban. It also throws in there that Uber should support its immigrant drivers by adding a tipping option to the app.

“As a company whose success is built on a foundation of hard work by immigrant workers, Uber can and should do better to stand up for immigrants and their workers,” said IDG founder Jim Conigliaro. “As a show of solidarity with the thousands of immigrants who helped build this company, we are calling on Uber’s CEO Travis Kalanick to immediately step down from President Trump’s advisory council in protest of his immigration and Muslim travel ban.”

So far, more than 250 have signed the online petition, with new signatures appearing every minute.

The petition comes in the midst of the #deleteUber movement, in which disgusted customers have been deleting the app in droves after learning that the company continued to send cars during a taxi strike that was taking place at JFK Airport — where numerous refugees were being detained over the weekend — by failing to turn off its app to prevent dropoffs and pickups there.

Uber officials responded with words of support for its drivers, but stopped short of saying Kalanick would step down from Trump’s team.

“More than ever, it’s important that we all support freedom of speech. Like many others, Uber strongly opposes the president’s unjust immigration ban which is harming many innocent people, many of whom are drivers,” said a company spokesperson. “That’s why we created a $3 million legal defense fund to help, and why we’re offering compensation for lost earnings for any driver stranded abroad. We will continue to stand up for those being hurt by the president’s executive order.”
