Live updates: Trump says aides ‘probably' won't use Signal anymore

What to Know

• Director of National Intelligence Tulsi Gabbard and CIA Director John Ratcliffe faced a grilling at a Senate Intelligence Committee oversight hearing Tuesday.
• The hearing came after The Atlantic’s editor-in-chief said he was accidentally included in a group chat about military strikes against the Houthis in Yemen.
• In an exclusive interview with NBC News, President Donald Trump said he is standing by national security adviser Mike Waltz, whose team Trump said was responsible for adding Goldberg to the chat.
• Speaking later from the White House, Trump downplayed the events and said the chat contained “no classified information, as I understand it.” The president said aides would “probably” not use Signal any longer. 
• Also today, Trump’s nominee to head the Social Security Administration, Frank Bisignano, testified at his Senate confirmation hearing on cuts to the agency and talk of privatization.
• And the White House said that Russia and Ukraine had agreed to a ceasefire in the Black Sea and to implement a ban on attacks on energy facilities by the two neighbors, an apparent breakthrough after American negotiators held separate talks with both countries.
