Trump threatens airstrikes in response to alleged chemical attack in Syria
President Trump tweeted early Wednesday that Russia should "get ready" for incoming U.S. missiles in Syria. The president vowed a response to last weekend's suspected chemical attack carried out by Syrian government forces that killed dozens of civilians. In spite of President Trump's tweet, White House press secretary Sarah Sanders said Wednesday that all options are on the table for a U.S. response. CBS News national security correspondent David Martin joins CBSN to discuss how the U.S. could retaliate.
