According to Axios, investigators became so alarmed by Fang’s behavior and activities that they alerted Swalwell in 2015 to their concerns, and gave him a “defensive briefing.” Swalwell then cut off all ties with Fang and has not been accused of any wrongdoing, according to an official who spoke to the outlet.

Swalwell, who was one of the most outspoken lawmakers who pushed the Russia collusion narrative since Trump took office, is now hinting that the president was behind Axios’ explosive reporting during an interview with Politico.

“I’ve been a critic of the president. I’ve spoken out against him. I was on both committees that worked to impeach him. The timing feels like that should be looked at,” Swalwell said on Tuesday.
