Sen. Dick Durbin (D-Ill.) called out Sen. Majority Leader Mitch McConnell (R-Ky.) on Tuesday, saying he is either choosing to ignore “our intelligence agencies” or feels incentivized to aide Russian interference as a beneficiary.

Rebuking the majority leader’s “case closed” view on the Mueller report, Durbin explained the two potential scenarios of why McConnell is so antsy to move on, saying either “he really doesn’t believe it, he doesn’t think the Russians were involved in 2016. He ignores the Mueller report and our intelligence agencies.”

“Or in the alternative, feels the Russians were on the side of the Republicans in 2016 and just might be again in 2020,” Durbin added, expressing his hopes that the “latter possibility is so remote as to being impossible.”

Following Sen. Elizabeth Warren‘s (D-Mass.) call for impeachment on the Senate floor, Durbin struck a similar tone to Sen. Chuck Schumer (D-N.Y.), who condemned McConnell for “whitewashing” the Mueller report, saying “this isn’t over and it won’t be over soon.”

Leader McConnell has made clear he and Senate Republicans want the Mueller Report to disappear. With so many troubling questions unanswered, Senate Rs and AG Barr must not be allowed to sweep this under the rug. We must hear testimony from Robert Mueller and Don McGahn.

“Leader McConnell has made clear he and Senate Republicans want the Mueller Report to disappear,” he wrote on Twitter, emphasizing that “With so many troubling questions unanswered, Senate [Republicans] and AG Barr must not be allowed to sweep this under the rug.”

“We must hear testimony from Robert Mueller and Don McGahn,” Durbin concluded.

Although a plethora of Republicans is dead-set on moving on from the Mueller report, Durbin has “reintroduced the bipartisan DETER Act,” garnering unlikely support from Sen. Lindsey Graham (R-S.C.), who has been continually backpedaling from his original stance that “it’s over.”

Reintroduced the bipartisan DETER Act w/@LindseyGrahamSC. It prohibits foreigners who improperly interfere in our elections from coming to the US to further their schemes & bars them from entering our country in the future. This is a must-pass bill in light of the Mueller Report.

If passed, “it prohibits foreigners who improperly interfere in our elections from coming to the US to further their schemes & bars them from entering our country in the future.”

However, with McConnell at the helm, it’s likely that this bipartisan bill will face challenges as he is known for making the Senate his “legislative graveyard” by blocking many pieces of legislation that he doesn’t agree with.
