In the wake of a New York Times report detailing its ties to the Chinese regime, Code Pink and its allies on the far left have decried the “new-McCarthyism” that they say is poisoning the political discourse. But those complaints are not enough to block further scrutiny of this network of activist groups: Senator Marco Rubio is now asking the Justice Department to step in and investigate the matter.

He wrote yesterday to Attorney General Merrick Garland, citing the Times’ reporting and demanding a DOJ investigation into Code Pink and eight other organizations funded by Neville Roy Singham, a tech mogul who now resides in China and attends Chinese Communist Party propaganda-coordination sessions.

“Combatting Beijing’s malign influence must be a key objective for the U.S. Department of Justice (DOJ). Unfortunately, it appears the DOJ is either unaware or ambivalent to this growing threat,” Rubio wrote.

His letter to Garland recapitulates the findings from the Times report, namely, that Singham uses a constellation of shadowy nonprofit groups registered to UPS store mailboxes through which he routes donations to pro-CCP organizations in the U.S. and elsewhere. These include “No Cold War,” a group that, like Code Pink, promotes Beijing’s talking points, and Dongsheng News, a New York-based outlet that also backs the Party’s line.

Rubio also said that the Justice Department should scrutinize Singham’s business ties: “Corporate documents show that in 2019, Mr. Singham started a consulting business with a group of entities located in the PRC. Those partners are active in the propaganda apparatus, co-owning with the municipal government of Tongren a media company that promotes CCP policies.”

The senator said that Garland should investigate the groups in question for potential violations of the Foreign Agents Registration Act.

“The CCP is our greatest adversary, and we cannot allow it to abuse our open system to promote its malign influence any longer,” Rubio wrote.

In addition to decrying the Times‘ report as McCarthyist, Code Pink denied that the group takes direction from China.

Code Pink co-founder Jodie Evans, who is married to Singham, per the Times report, told the paper, “I deny your suggestion that I follow the direction of any political party, my husband or any other government or their representatives. I have always followed my values which has often resulted in being arrested 75 times.”
