Pro-life law firm files letter against Elizabeth Warren over heated rhetoric towards pregnancy centers

First Liberty Institute filed a letter against Sen. Elizabeth Warren, D-Mass., for her heated rhetoric against pregnancy centers that have been the target of several violent attacks.

The First Liberty Institute represents Heartbeat International, responded to the letter prior to their deadline of Oct. 3 with a condemnation of the request as an "inappropriate" use of the Senate’s power.

"While we appreciate your interest in the important work of Heartbeat International, we are aware of no law or legal instrument that would authorize you to conduct an investigation of this private, religious nonprofit, much less compel them to answer your questions. Rather, your letter appears to be an unwarranted effort to investigate a private organization which holds to a religious and ideological opinion with which you disagree. The United States Supreme Court firmly rebuked such actions over 60 years ago. United States Senators should not use the power of their office to harass private citizens in hopes of creating conflict for legislative solutions otherwise wanting for a problem to solve. Your questions are neither appropriate, nor germane," the letter read.
