Sen. Martha McSally wants to make domestic terrorism a punishable crime in the wake of two mass shootings potentially tied to ideologically motivated violence in California and Texas.

McSally, R-Ariz., intends to introduce legislation when the Senate returns from the summer recess to create a law in the federal criminal code to address domestic terrorism.

Federal authorities use other laws, such as weapons offenses and hate crimes, to charge such acts.

McSally said in a written statement to The Arizona Republic that it is important to call domestic terrorism by its name — and to create laws to address it as such.

The FBI first started investigating Justin Olsen, 18, in February when a user with the handle “ArmyOfChrist” posted threats in the chat room iFunny, according to an affidavit obtained by The Vindicator. The account was eventually traced back to Olsen’s computer, the affidavit states. After his arrest, Olsen admitted to posting under the screen name, the FBI said.

Officials say ArmyOfChrist posted about his support of mass shootings as well as attacks on Planned Parenthood. In June, ArmyOfChrist wrote “in conclusion, shoot every federal agent on [site],” during a discussion with another user about the 1993 siege on a Branch Davidian compound in Waco, Texas, according to the affidavit.
