On Thursday, Sen. Richard Blumenthal (D-CT) was asked by MSNBC's Mark Halperin about the continuing investigation into possible collusion between the Trump campaign and Russia. His answer was informative:

BLUMENTHAL: Ultimately, the question is: What did the president know and when did he know it?

HALPERIN: Senator, when will this process conclude?

BLUMENTHAL: I think it will conclude when we conclude that we've uncovered all of the evidence of potential compromises of the Department of Justice. It's our oversight responsibility to determine whether there was any kind of wrongdoing relating to that Department of Justice investigation, and we're going to continue working until we uncover all the evidence that may exist of obstruction of justice, of collusion between the Trump campaign and the Russians in interfering in this election. And we're determined to get at the truth.

The problem with the way in which Blumenthal frames his answer, as noted by David Rutz of The Washington Free Beacon, is that the phrase “may exist” leaves the door open to an indefinite investigation.

The world of politics is carefully designed, and this is no different.

It is highly unlikely that the investigation into possible collusion between the Trump campaign and Russia will reach any definitive conclusion until well after the 2018 mid-term elections – and perhaps even the 2020 presidential election. This way, any and all allegations against President Trump and those around him, whether truth or fiction, will taint the Republican Party, helping the Democrats gain votes.
