Here are 3 big things you need to know—

One — The State Department says someone used an AI-generated voice of Secretary of State Marco Rubio to contact U.S. and foreign officials. The person contacted three foreign ministers and two U.S. officials in mid-June via the Signal messaging app and left voicemails for at least two of them.

Two --- Michigan Senate Minority Leader Aric Nesbitt is calling for the federal government to investigate a growing scandal involving the Michigan Economic Development Corporation. The MEDC gave a 20-million-dollar grant to Fay Beydoun, an associate of Governor Whitmer, and she is accused of misusing the money. Nesbitt says official email records show she communicated directly with Whitmer's office to obtain the grant, and top MEDC officials not only knew about the arrangement, but also attempted to hide and withhold evidence from investigators.

And number three --- The largest earthquake swarm in 16 years has rumbled under Mt. Rainier in Washington State. Hundreds of small earthquakes were felt across a wide area of the mountain. The U.S. Geological Survey says the earthquakes alone aren't cause for concern. There's no other unusual activity on the mountain.
