MSNBC anchor Joe Scarborough on Tuesday demanded to know why news outlets didn't question how Christine Blasey Ford's confidential letter about Supreme Court Justice Brett Kavanaugh surfaced in the press, after many Republicans have speculated that it came from the Democrats.

"What New York Times reporter, what Washington Post reporter was assigned a story by their editors to go see what really happened with Dianne Feinstein, and that's Dianne Feinstein and her staff," Scarborough said during Tuesday's episode of "Morning Joe." "The sort of questions that would have happened if the Republican Party had done the same thing. Not one."

Ford sent a letter in July to Rep. Anna Eshoo, D-Calif., in which she alleged Kavanaugh sexually assaulted her in 1982 when the pair were teenagers. The letter was then forwarded to Feinstein, another California Democrat, who is the party's highest ranking member on the Senate Judiciary Committee.

But Ryan Grim, the journalist from the Intercept who first reported on the letter, said on Twitter he did not receive it from Feinstein's aides. His report prompted Feinstein to announce she had referred the matter to the FBI.

While Scarborough on Tuesday said Senate Judiciary Republicans led by Sen. Chuck Grassley, R-Iowa, had "acted shamefully" in how they managed Ford's accusation, he added that the same description could be applied to Democrats on the panel as well as outlets covering the controversy by not trying to ferret out who leaked the name.

"Look at yourself, and ask yourself the question: 'Why didn't we report on this in real time when you sure as hell would have reported on it if Grassley and his office had done the same thing?'" Scarborough said to editors, regarding the letter's leak. "Journalists in America have a lot to answer for. Why couldn't they play this down the middle?"
