U.S. Secretary of State Marco Rubio was visiting El Salvador on Monday to press a friendly government to do more to meet Trump administration demands for a major crackdown on immigration amid turmoil in Washington over the status of the government’s main foreign development agency.

The secretary of state said the United States could take steps to “protect its rights.” Panama’s leader said he was sure that President Trump wouldn’t seize the canal.

U.S. Secretary of State Marco Rubio met with Panama's president Sunday and warned the increased presence of Chinese companies and interests along the Panama Canal is "a threat" and the U.S. could take "measures necessary to protect its rights" unless changes are made.
