Trump: 'Nothing is off the table' in response to Iran's missile test

Trump made the comment on Thursday in response to a question by a reporter about whether he would consider military options to respond to Iran, a day after his national security adviser Michael Flynn put Tehran on "notice."

The White House also said Thursday it would respond to Iran's ballistic missile test.

"We will have further updates for you on those additional actions, but clearly (Flynn) warned to make sure that Iran understood that they are on notice that this is not going unresponded to," White House spokesman Sean Spicer told reporters.
