House Oversight Committee Chairman Jason Chaffetz (R-UT) said on Tuesday that his panel will not investigate the circumstances that led to former national security adviser Michael Flynn’s resignation.

“I think that situation has taken care of itself,” Chaffetz told reporters, as quoted by The Hill. “I think he did the right thing stepping down.”

Chaffetz’s office did not respond to multiple requests for comment by TPM.

Chaffetz said that the House Intelligence Committee is investigating Russian hacks related to the 2016 election and that the circumstances of Flynn’s resignation do not fall under the “purview” of his committee.

“It’s not something the Oversight Committee can actually look at because sources and methods are the exclusive purview of the Intel Committee,” he said.

House Intelligence Committee Chairman Devin Nunes (R-CA) said earlier Tuesday that he does not plan to investigate Flynn’s conversations with Trump about his calls with Russia’s ambassador to the United States.

Flynn resigned from his role as White House national security adviser late Monday after questions arose about conversations he had with Russian Ambassador Sergey Kislyak before Trump took office.

Current and former U.S. officials told news outlets last week that Flynn and Kislyak discussed U.S. sanctions during a call before Trump’s inauguration. Members of the President’s administration, including Vice President Mike Pence, previously denied that Flynn and Kislyak discussed sanctions.
