President Donald Trump and Minnesota Gov. Tim Walz have spoken over the phone about the shooting at a Minneapolis Catholic school, a White House official confirmed.

Trump called to offer his condolences to the people of Minnesota and Gov. Walz thanked him for the support, a source familiar with the call told ABC News. Trump didn't call after Minnesota state representative Melissa Hortman was assassinated in June, the source said.

President Donald Trump said he's been briefed on a shooting at a Catholic school in Minneapolis.

"I have been fully briefed on the tragic shooting in Minneapolis, Minnesota. The FBI quickly responded and they are on the scene. The White House will continue to monitor this terrible situation. Please join me in praying for everyone involved!" Trump wrote on his social media platform.

There are multiple victims from the shooting, which unfolded during morning drop-off at Annunciation Catholic School, sources told ABC News.

President Donald Trump on Wednesday said billionaire George Soros and his son should be charged under the RICO Act.

"George Soros, and his wonderful Radical Left son, should be charged with RICO because of their support of Violent Protests, and much more, all throughout the United States of America," Trump wrote on his social media platform.

"Soros, and his group of psychopaths, have caused great damage to our Country! That includes his Crazy, West Coast friends. Be careful, we’re watching you!" Trump added.

Soros' Open Society Foundations said Trump's accusations are "outrageous and false."

"The Open Society Foundations do not support or fund violent protests. Our mission is to advance human rights, justice, and democratic principles at home and around the world," the statement read. "We stand for fundamental freedoms guaranteed by the Constitution, including the rights to free speech and peaceful protest that are hallmarks of any vibrant democracy."
