White House Press Secretary Sean Spicer on Tuesday demanded a journalist stop shaking her head while he answered a question during the daily press briefing.

April Ryan, the Washington bureau chief for American Urban Radio Networks, asked Spicer how the administration would work to revamp its image amid investigations of potential ties to Russia, mentioning a report that Trump officials tried to stop former acting Attorney General Sally Yates from testifying on links between Trump’s campaign staff and Russian officials.

Spicer accused Ryan of having an agenda, arguing “if the president puts Russian salad dressing on his salad tonight, somehow that’s a Russian connection.”

“It seems like you’re hell-bent on trying to make sure that whatever image you want to tell about this White House stays,” Spicer argued later.

Ryan interrupted to further question Spicer, and as their exchange continued, the press secretary ordered Ryan to stop shaking her head while they talked.

Ryan tweeted after the briefing ended:

She also appeared on MSNBC to discuss the moment, saying “you cannot ignore as a reporter” the issues she questioned Spicer about.

“Sean is being the White House press secretary, talking about and trying to make this administration look better than what it does right now, and unfortunately I was road kill today,” Ryan said.
