Presumptive Republican Presidential candidate, Donald Trump, has a love/hate relationship with the press. While Trump loves the publicity he garnishes from the media, he hates the Washington Post's coverage. He made this clear, earlier this week, when he banned the Washington Post from covering his campaign events.
Following the mass shooting early Sunday morning, in Orlando, Trump said that Obama "either is not tough, not smart, or he's got something else in mind." This was based on the fact Obama neglected to tie the mass shooting to "radical Islamic terrorism." The shooting at the Orlando gay nightclub killed 49 people and left even more wounded.
Originally the Washington Post posted a headline reading, "Donald Trump suggests President Obama was involved with Orlando shooting." They later updated the headline to, "Donald Trump seems to connect President Obama to Orlando shooting." According to the Post the headline was changed to better reflect statements made by Trump. The change was in no way a response to the outcry by Trump or his supporters.
This is not Trumps first run in with the Post. Previously, Trump donated $1 million to veteran groups, but only after reporter David Farenthold pressed Trump for details about donations he promised to make. Following the donation Trump held a press conference where he detailed his distain for Farenhold and ultimately the Post in general.
