Americans in Washington DC are reacting to a Signal group chat leak where a journalist was inadvertently added to a chat where US national security officials discussed a planned military strike.
The revelation has raised questions about why high-ranking officials discussed such sensitive matters on a potentially vulnerable civilian app.
US Director of National Intelligence Tulsi Gabbard and CIA Director John Ratcliffe denied at a Senate hearing that any classified information was shared in the message chain.
The Senate Foreign Relations Committee is expected to investigation the incident.
