A new book out Tuesday alleges that the Biden administration’s relative “silence” on the fentanyl crisis ravaging states across the country is because of the Biden family’s connections to China, which is responsible for a large portion of fentanyl imports.

Author Peter Schweizer, who has written several investigative bestsellers, including “Clinton Cash” and “Red Handed,” just released “Blood Money: Why the Powerful Turn a Blind Eye While China Kills Americans,” a new book that details “bombshell after bombshell, exposing the Chinese Communist Party’s covert operations in the American drug trade, social justice movement, and medical establishment to sow chaos and deca­dence in the United States.”

In one chapter of the book, which was reviewed by Fox News Digital, Schweizer says the Biden administration has not taken “aggressive action” against China combating the fentanyl crisis, which the administration has previously said “bears responsibility.”

“Joe Biden was outspoken in 1992 when it was exposed that Beijing was involved with the heroin trade.
