President Donald Trump was expected to spend the fall pushing his ambitious tax reform agenda and helping devastated regions in Texas, Florida and Puerto Rico recover from hurricanes.Instead, over a period of three weeks, Trump has hammered the NFL into submission over the national anthem protests, repeatedly attacked the “fake news” media and now reopened a fight over his – and his predecessor’s – handling of Gold Star families.But these seeming distractions are the president’s substance – and the legislative agenda his predecessors have approached with a singular focus is, for him, largely a diversion.
