Chris Cuomo had previously apologized for advising Andrew Cuomo’s senior political aides — a breach of traditional barriers between journalists and lawmakers — but thousands of pages of new evidence released on Monday by the New York attorney general, Letitia James, revealed that the anchor’s role had been more intimate and involved than previously known.

“The documents, which we were not privy to before their public release, raise serious questions,” CNN said in a statement on Tuesday.

“When Chris admitted to us that he had offered advice to his brother’s staff, he broke our rules and we acknowledged that publicly,” the network said. “But we also appreciated the unique position he was in and understood his need to put family first and job second. However, these documents point to a greater level of involvement in his brother’s efforts than we previously knew.”

“As a result, we have suspended Chris indefinitely, pending further evaluation,” the network said.
