NBC News reported on Sunday that Special Counsel Robert Mueller has gathered enough evidence to charge former National Security Adviser Michael Flynn and his son, Michael G. Flynn.

According to NBC News:

Federal investigators have gathered enough evidence to bring charges in their investigation of President Donald Trump's former national security adviser and his son as part of the probe into Russia's intervention in the 2016 election, according to multiple sources familiar with the investigation.

Mueller is applying renewed pressure on Flynn following his indictment of Trump campaign chairman Paul Manafort, three sources familiar with the investigation told NBC News.

The investigators are speaking to multiple witnesses in coming days to gain more information surrounding Flynn's lobbying work, including whether he laundered money or lied to federal agents about his overseas contacts, according to three sources familiar with the investigation.

Mueller's team is also examining whether Flynn attempted to orchestrate the removal of a chief rival of Turkish President Recep Erdogan from the U.S. to Turkey in exchange for millions of dollars, two officials said.

Three sources told NBC that Michael Flynn's son could be charged at the same time as his father.
