Trump downplays group chat where military plans were discussed

President Donald Trump is downplaying the Signal group chat where secret American airstrikes were discussed for days by top officials in the presence of The Atlantic editor-in-chief Jeffrey Goldberg, who was inadvertently invited to the chain. National security adviser Mike Waltz, who says he created the group chat, is now taking "full responsibility" for his actions. NBC’s Garrett Haake reports for TODAY.
