As Ivanka Trump arrived on Capitol Hill ready to discuss parental leave with lawmakers on Tuesday, Sen. Marco Rubio (R-Fla.) decided to greet the first daughter and adviser to the president with a hug.

Based on a photograph that circulated in Twitter, Trump was, well, not into it. She looked stiff as a board in the photo taken by an Associated Press reporter — arms at her side, looking past Rubio through her oversized sunglasses.

Throughout the day, Twitter had a field day with the cringe-worthy photo.

One person captioned the photo with alternative lyrics from the TLC song “No Scrubs.”

Some called Rubio thirsty.

Others suggested Trump had no idea who was trying to hug her.

But instead of being the butt of yet another joke, Rubio joined in on the fun, opening “an investigation” to learn the truth about the “failed hug.”

He then tweeted that additional photographic evidence would shed light on the ordeal.

Somehow the senator acquired a different angle of the photo, though just what it proved remained unclear.

He concluded that the “press covfefe of the alleged failed hug” was false — “covfefe” being a reference to a mysterious and still unexplained tweet on May 31 by President Trump.

Ivanka Trump herself joined in on the Twitter action and wrote, “Anonymous sources say @marcorubio planned the alleged failed hug. I have no comment (but I would have hugged him anyway!)”
