According to a report by Reuters on November 15, two Democratic senators said in a letter seen by Reuters reporters on the 15th that the Pentagon and law enforcement agencies should investigate reports that billionaire Elon Musk had made multiple calls with Russian officials, including Putin, for national security reasons. "These relationships between a well-known enemy of the United States and Mr. Musk, the beneficiary of huge sums of money from the U.S. government, will raise serious questions about Mr. Musk's reliability as a government contractor and classified person," the two senators wrote in a joint letter dated the 15th. According to reports, since the Wall Street Journal reported on the so-called liaison activities last month, several Democratic lawmakers have publicly called for an investigation into Musk's communications with Moscow, but the letter to government officials with the authority to initiate such investigations has not previously appeared in the newspapers.
