The United States is still probing the murder of Saudi journalist Jamal Khashoggi, Secretary of State Mike Pompeo said on Monday, as U.S. lawmakers continued to demand stronger U.S. action to punish the perpetrators, Reuters reported.

“America is not covering up for a murder,” Pompeo said during a visit to Hungary, adding that the United States would take more action to hold accountable all those responsible for the U.S.-based journalist’s death inside the Saudi consulate in Istanbul in October.
