White House Deputy Chief of Staff Katie Walsh has been exposed as the source of a number of recent leaks from the Trump Administration, according to reports.

The story was first broken by GotNews—who didn’t reveal their source, but said it was “100% reliable.” Walsh has, apparently, been leaking damning stories from inside the West Wing to The New York Times and other media outlets.

Their source, described as a White House senior aide, told GotNews that Walsh is referred to in the White House as “Madame President”—but “it isn’t a compliment.”

The source, who is allegedly close to President Trump, said: “Everyone knows not to talk to her in the White House unless you want to see it in the press… The only question is whether or not she’s doing it at the behest of [Trump’s Chief of Staff] Reince Priebus or if she’s doing it to advance herself in DC media circles.”

The source added: “The president and his allies have been deliberately feeding her fake information in order to find her network. It’s been going well.”

A White House investigation into Walsh’s dealings with the media is planned, according to the source. In the meantime, Walsh continues to work inside the White House, in her role as Deputy Chief of Staff.
