Senator Joni Ernst says she will not vote to confirm President Obama’s nominee to be the nation’s next attorney general. Loretta Lynch is Obama’s pick to replace outgoing Attorney General Eric Holder.

“I have some very serious concerns with Loretta Lynch,” Ernst says, “especially during her testimony when she had stated that she does uphold what the president has done and his decisions, especially when it comes to executive amnesty.”

Last Thursday, Iowa’s other U.S. Senator, Chuck Grassley, was among the Republicans who voted against advancing Lynch’s nomination out of the Senate Judiciary Committee, but Lynch got the votes of three other Republicans and her nomination is now eligible for a vote in the full Senate.

Lynch is currently serving as the U.S. Attorney in Brooklyn and her office led the investigation which resulted in last week’s arrest in Brooklyn of three men who intended to go to Syria to join the Islamic State. Despite his vote against Lynch’s nomination in committee, Senator Grassley has said he expects she will be confirmed by the full senate. She would become the first African American women to serve as U.S. Attorney General.
