EXCLUSIVE: Sen. Tom Cotton, R-Arkansas, said Thursday that U.S. Attorney General Merrick Garland should resign over the Biden administration Justice Department’s inaction on more than 50 attacks on pro-life pregnancy centers and churches in recent weeks purportedly carried out by Jane’s Revenge.

In a letter sent to Garland, Cotton, who is the ranking member for the subcommittee on Criminal Justice and Counterterrorism, the Intelligence Committee, and the Armed Services Committee, also called on the DOJ to investigate Jane’s Revenge as a "domestic terrorist organization."

"Houses of worship and pro-life pregnancy centers are under attack. The Family Research Council has compiled a list of more than 50 attacks against churches, pro-life pregnancy centers, and other pro-life groups in the past few weeks," Cotton wrote to Garland in a letter exclusively obtained by Fox News Digital. "A left-wing extremist group called ‘Jane's Revenge’ has taken credit for many of these attacks, including firebombings and grotesque acts of vandalism." 

Cotton noted how the same group on Tuesday "has now issued a letter declaring ‘open season’ on all so-called ‘anti-choice’ groups, and calls for terrorist attacks against these groups by anyone ‘with the urge to paint, to burn, to cut, [or] to jam."

The senator included a list of more than a dozen attacks that Jane’s Revenge has claimed responsibility for in recent weeks following the leak of a Supreme Court draft opinion in the case of Dobbs v. Jackson Women’s Health Organization that if published, would overturn Roe v. Wade. Given many of these attacks did not result in any arrests, Cotton said the DOJ should bring federal charges against the perpetrators.

"What is the Department of Justice doing to protect Americans from these violent attacks? At a minimum, you should bring federal charges3 against the perpetrators, where appropriate, and investigate ‘Jane's Revenge’ as a domestic terrorist organization, Cotton wrote. 

"If you are unwilling to protect Americans from these attacks, you should resign-although, in my opinion, you should resign in any case," he added. 

The list at the end of a letter noted that on May 7, St. John XXIII Catholic Church in Ft. Collins, Colorado, had its windows smashed and was vandalized with the message, "My Body My Choice," plus an anarchist symbol. The next day, Wisconsin Family Action in Madison, Wisconsin is firebombed and vandalized with the threat, "if abortions aren't safe, then you aren't either."
