congresswoman cheney seems to be suggested the committee is headed into territory they expect they will elicit evidence that will warrant obstruction charges against the president and if that's the case refer it to the justice department and ask doj to consider prosecution. >> so the statute that representative cheney appears to be referencing in her comments this week. how it reads. whoever corruptly obstructs, influences or impedes any official proceeding or attempts to do so shall be fined under this title or imprisoned not more than 20 years or both. a federal judge upheld the doj's use of this sage statute against two rioters last week. based on that, joyce, could the statute be successfully used to charge the former president? >> like always, alex, depends on the evidence. but it's good news that there's precedent in the lower courts
