Schiff: Real question is if Trump is under the influence of a foreign power
Whether Mueller will answer that question is unclear. But House Intel Chair Adam Schiff said he is steering his probe in a new direction to focus on it.
But legal experts, along with the congressman leading the House Russia investigation, tell NBC News that the most important question investigators must answer is one that may never have been suitable for the criminal courts: Whether President Trump or anyone around him is under the influence of a foreign government.
"It's more important to know what Trump is NOW than to know what he did in 2016," said Martin Lederman, professor at the Georgetown University Law Center and former deputy assistant attorney general in the Department of Justice's Office of Legal Counsel during the Obama administration. "It's more important to know whether he has been compromised as president than whether his conduct during the campaign constituted a crime."
