Twitter users jumped on the moment, comparing it to other well-known awkward hugs.
Rubio began tweeting that he was launching an “investigation” into the hug and the resulting photo.
“Just left Intel comm & informed meeting 2day with @IvankaTrump blowing up twitter over alleged failed hug! Investigating. Will respond soon,” Rubio tweeted.
Fresh off his Senate Intelligence Committee meeting, Rubio said he had “unclassified” evidence of the incident.

Of course, witnesses were sought.
And then — the evidence! Rubio tweeted another shot of the encounter, this one with both his and Trump’s faces a blur.
Rubio even managed to slip in a "covfefe," a reference to a cryptic late-night tweet sent by President Donald Trump.
Trump soon tweeted her own response to the “investigation.”
“There really needs to be more hugs in politics... even failed ones,” Trump’s brother, Donald Trump Jr., later tweeted.
