Mitch McConnell may just have gotten himself added to Robert Mueller's witness list.

The mountain of evidence that Donald Trump and his campaign engaged in a conspiracy with the Russian government got a whole lot higher this week.

And the case against Trump for obstruction of justice, which was already all but a slam dunk, may have gotten even stronger Sunday morning.

The day after Trump implicated himself on Twitter, Senate Majority Leader Mitch McConnell appeared on This Week with George Stephanopoulos, and was asked to respond to new reports that Trump pressured Republican leaders to abandon the Russia investigation.


McConnell's responses could scarcely have been more incriminating.

"Well, I don't think the president said anything to me on this subject that I considered inappropriate," McConnell insisted, repeating the line without any prompting.

And when Stephanopoulos directly asked McConnell if Trump had tried to "curtail" the investigation, his evasion was deafening:

STEPHANOPOULOS: Several reports that President Trump has been upset with the Senate investigation, called you and other senators trying to get it ended as quickly as possible, trying to curtail it. Senator Dianne Feinstein, Democratic Senator Dianne Feinstein, said this is inappropriate interference in your investigation. What did the president say to you about this? And how did you respond? MCCONNELL: Well, I don't think the president said anything to me on this subject that I considered inappropriate, so I have no criticism of the conversations that we may have had about this or other issues. He hasn't said anything to me that I thought was inappropriate. STEPHANOPOULOS: Has he tried — MCCONNELL: And the investigation is going forward in the Senate on a bipartisan basis. That's the way I felt we ought to handle this. And I think Senator Burr and Senator Warner are doing just fine. STEPHANOPOULOS: So, the president has not tried to curtail this investigation? MCCONNELL: He has not said anything to me that I think is inappropriate.

That kind of response might get you out of a tough TV news spot, but it also appears to indicate that Trump may have attempted to influence McConnell, which is sure to get the attention of the special counsel.

In fact, the only thing that might keep McConnell and his fellow Republicans out of Robert Mueller's witness chair is the fact that Trump has already been so open about his obstruction of justice.
