President Donald Trump appeared to focus on immigration and energy in his first executive orders following his inauguration.

This is where Mr Trump’s talk of an “invasion” becomes more than rhetorical bombast. Framing the cartels as terrorists invading America is meant to legitimise his use of the law. And because America is being invaded, Mr Trump argues, he can block anyone from crossing the border. The courts may not see it that way. ■

President Trump’s executive orders this week outline a sweeping agenda, from declaring an invasion at the border to curtailing birthright citizenship. But significant questions remain about what’s next.
