How serious are obstruction charges?
Jun 13, 11:20 AM EDT
Of all the federal charges that former President Donald Trump and his aide Walt Nauta face in the investigation into the alleged mishandling of top secret government documents, obstruction is one of the most serious, according to legal experts.
Claire Finkelstein, the founder and faculty director of the Center for Ethics and the Rule of Law at the University of Pennsylvania’s Annenberg Public Policy Center, noted that the obstruction charges in the indictment against Trump and his aide carry as much serious weight as the charges related to keeping the top secret documents, with a maximum penalty of 20 years in prison.
TIMELINE: Events leading to Donald Trump’s indictment in classified documents case
Finkelstein said an obstruction charge can cover a broad range of alleged activities, from as simple as lying to investigators, to as major as destroying evidence. But she said it all comes down to one clear allegation: that the accused deliberately interfered with an ongoing criminal investigation.

The federal indictment against former President Donald Trump alleges that he willfully retained documents containing the nation’s most sensitive secrets, including nuclear programs, after he left office, showed some of them on at least two occasions and then tried to obstruct the investigation into their whereabouts.
Federal prosecutors allege that the classified documents included “defense and weapons capabilities of both the United States and foreign countries; United States nuclear programs; potential vulnerabilities of the United States and its allies to military attack; and plans for possible retaliation in response to a foreign attack.”
Boxes of the documents were allegedly stored in locations around Trump’s Mar-a-Lago club, including a ballroom stage and a bathroom, according to prosecutors.
