President Donald Trump on Wednesday ignored shouted questions about his administration’s reported ties to Russia.

During a joint press conference with Israeli Prime Minister Benjamin Netanyahu at the White House, Trump took two questions from U.S. media outlets about the Israeli-Palestinian peace process and the Iran nuclear deal.

Neither of those questions centered on Russia ― the biggest issue this week that ultimately led to the resignation of Trump’s National Security Adviser Michael Flynn, who served less than 30 days at the post.

When CNN’s Jim Acosta tried to ask Trump about Flynn, the president smiled, thanked the audience and walked away.

Wednesday’s event marked the third straight press conference where reporters were not able to ask the president about the biggest issue of the day. Trump has mostly called on friendlier outlets in the conservative space: The New York Post, Fox News, Sinclair’s ABC7, The Daily Caller, Christian Broadcasting Network and Townhall.com.

Appearing on MSNBC after the press conference, Senate Intelligence Committee Vice Chair Mark Warner (D-Va.) said the public remained in the dark about Trump’s administration and Russia.

“We don’t know what the president knew and when he knew it,” he said.
