President Donald Trump's plan to deploy the military on U.S. soil is sparking conflict with blue state governors that is playing out in the courts.

WASHINGTON The day he declared the COVID-19 pandemic a national emergency, President Donald Trump made a cryptic offhand remark. That prompted 10 senators to look into how sweeping Trump believes his emergency powers are. They have asked to see this administration's Presidential Emergency Action Documents, or PEADs. The senators think the documents would provide them a window into how this White House interprets presidential emergency powers. The most publicized example was Trumps decision last year to declare the security situation along the U.S.-Mexico border a national emergency.
