On 9 June 2016, President Barack Obama released a video formally endorsing Secretary Hillary Clinton for President:

 

In the clip, President Obama praised her and noted that he had to debate Clinton twenty times himself during their 2008 matchup. The President also noted that Clinton subsequently agreed to work with his administration as Secretary of State shortly after his election to the office. The clip wasn’t just notable because of the gravity of Obama’s stamp of approval — Twitter users deduced that the clip was likely filmed two days previously, due to the President’s attire:

Presumptive Republican nominee Donald Trump also took to Twitter to provide his take on the endorsement:

Clinton quickly returned the tweet:

Obama referenced having met earlier with Sen. Bernie Sanders about the party’s next steps in the election, a topic that came up at the day’s White House Press Briefing:

Sanders briefly spoke outside the White House as well:

During the briefing, White House Press Secretary Josh Earnest confirmed that President Obama filmed his endorsement of Hillary Clinton on 7 June 2016.
