“If it’s true that Trump tried to shut down the Russia investigation, and then fired Comey when he wouldn’t back off, that’s a pretty good example of obstruction,” Jens David Ohlin, a professor at Cornell Law School, said Wednesday. “Not only that, it’s the kind of corruption that historically has been the basis for an impeachment.”

But it’s only one memo, about one meeting, right?

No, it may be the tip of an iceberg.

A savvy bureaucrat, Comey reportedly prepared memos following other meetings or conversations with Trump and others. Investigators are already tracking this potentially longer paper trail, with the Republican chair of the House Oversight and Government Reform Committee asking the FBI this week to provide any related documents by May 24.

“If true, these memoranda raise questions as to whether the president attempted to influence or impede the FBI’s investigation as it relates to Lt. Gen. Flynn,” wrote Rep. Jason Chaffetz, R-Utah.

So if there’s a potential crime, who would investigate?

That’s the crucial question.

The House of Representatives and Senate Intelligence committees have ongoing investigations into alleged Russian interference with the 2016 U.S. presidential election. These could touch on Flynn’s actions, and potentially reach deeper into Trump’s team, but they are essentially civil rather than criminal proceedings. In such congressional investigations, the biggest legal consequence might result from a witness’s false testimony.

A blue-ribbon special commission or a bipartisan special congressional committee to investigate alleged Russian interference, as some in both parties have suggested, would likewise be more about fact-gathering than about prosecuting.
