That includes carrying out this threat."Trump appeared to issue a warning about bombing some of Iran’s civilian infrastructure in an effort to persuade the country to reopen the Strait of Hormuz, among other demands.

Democrats have been talking about impeaching President Trump since before he was even sworn into office," White House spokesman Davis Ingle said. "The Democrats in Congress are deranged, weak, and ineffective, which is why their approval ratings are at historic lows."Ocasio-Cortez’s plea to U.S. service members comes after the Department of Justice opened an investigation in 2025 into six Democratic lawmakers who appeared in a video urging troops and members of the intelligence community to reject "illegal" orders from the government.
