White House plans to take action targeting left-wing groups as early as this month

The response to Charlie Kirk's assassination is expected to include investigations into the tax-exempt status of certain liberal organizations. Prosecutors have not indicated the alleged shooter was part of a group.

The administration is putting together plans to take action against left-wing groups that President Donald Trump and his allies accuse of fomenting political violence, according to three people familiar with discussions about the federal response to the Sept. 10 assassination of conservative activist Charlie Kirk in Utah. One of the sources said the moves could come as early as the end of the month.

The White House is "trying to move quickly while not rushing," the person said.

The actions, which are still being formulated, are expected to include investigations into the tax-exempt status of certain liberal organizations, the same source said. They were first reported by The Wall Street Journal.

“The White House is exploring a wide variety of options to address left-wing political violence and the network of organizations that fuel and fund it," an administration official said. “The emphasis and focus are on criminal actions,” the official added, “not political speech.”

Trump said on "Fox & Friends" last week that he wanted to launch a racketeering probe of groups funded by billionaire George Soros, the 95-year-old New York-based financier. Trump later told NBC News that Soros "should be put in jail."
