Meanwhile, President Trump and the White House continue to complain about the use of anonymous sources in news reports about the ongoing investigation into the Trump administration’s ties to Russia. This is White House Press Secretary Sean Spicer, speaking Tuesday about recent leaks about the investigation into Trump’s son-in-law and senior adviser Jared Kushner’s attempts to establish a back channel of communication with Russia.

Press Secretary Sean Spicer: “I’m not going to get into what the president did or did not discuss, but it—what your question assumes is a lot of facts that are not substantiated by anything but anonymous sources that are so far being leaked out.”

President Trump has also complained about the use of unnamed sources, tweeting over the weekend, “Whenever you see the words 'sources say' in the fake news media, and they don’t mention names, it is very possible that those sources don’t exist but are made up by fake news writers. #FakeNews is the enemy!” But on Tuesday, Trump retweeted a Fox News article based exclusively on a single unnamed source, who said Kushner did not discuss a possible back channel with Russia during a December meeting with Russian Ambassador Sergey Kislyak at Trump Tower.
