Internet reports that four people familiar with the matter revealed that after a public quarrel between Trump and Musk, the White House has instructed the Department of Defense and NASA to collect detailed information about SpaceX's multi-billion-dollar contract. People familiar with the matter said that the government has launched a review and asked relevant agencies to carefully review the contracts received by Musk and his company to prepare for possible retaliatory measures. The Pentagon is also assessing whether SpaceX's participation in the U.S.'s next-generation missile defense system project should be weakened. (Jin Shi)
