Marco Rubio came up against an unexpected border wall on Tuesday morning as he greeted Ivanka Trump at the US Capitol.

The man President Trump condescendingly called 'Little Marco' on the campaign trail made the decision to greet Ivanka with a hug when she entered the building, a decision that the First Daughter unfortunately did not make.

As a result, the Florida Senator appeared to be tumbling into a rigid Ivanka in a photo snapped at that moment, which once again showed a Trump towering over Rubio.

The photo was made even more awkward by the expressions of the pair, with Rubio flashing a giant smile and lvanka displaying a look of complete indifference.

She also had not yet taken her sunglasses off as she was just entering the building.

Even the Secret Service agent assigned to Ivanka seemed to be confused about what was happening, with the photo capturing the utterly perplexed look on the man's face.

Back in action: The pair were soon in sync again as they headed off to their meeting in the building

Soon after, the two appeared to move past their awkward meet-and-greet as they were seen walking down the hallway of the Capitol together on their way to a meeting.

Tuesday marked Ivanka's first trip to Capitol Hill in an official capacity, with the senior advisor to President Trump working on a paid family leave bill with Senator Rubio.

The Florida representative is the co-sponsor of a bill currently in the Senate that would give families a tax credit of $2,500 per child.

Ivanka meanwhile has long said that children and working mothers would be a big part of her platform when she arrived in Washington DC.

Ivanka was outfitted for the big day in a pair of Kellsee Pumps from her eponymous line, which retail for $140, and carrying her brand's $275 Tribeca Leather Satchel.

Also part of her line were the $32 Open Drop Earrings she wore with her dark-green silk t-shirt dress.

She made a stealthy exit from her Kalorama home earlier in the day, electing to depart from a waiting SUV in the garage rather than walk out in front of the house.

That was not the case with husband Jared Kushner however, who put on a grinning and leggy display as he strutted down the main stairwell of their $5million rental on Tuesday.

Jared's jovial jaunt to his waiting SUV came one day after he shocked the entire country by delivering his first public speech since arriving in Washington DC.

Stronger together: Rubio and Ivanka's father famously butted heads on the campaign trail

It was in February of last year when President Trump tore into Rubio with a little help Chris Christie, on the same day the New Jersey governor endorsed him for president.

'It’s one act after the other,' Christie said of the Florida Senator.

'We don't need any more of these Washington, D.C. acts. The problem is Washington, D.C., and we don’t need Washington politicians to come in and fix it.'

Trump said of Rubio; 'I watched a part of his little act and he’s a desperate guy. He’s a nervous nelly.

'I watched him backstage. He’s a mess. I've never seen a human being sweat like this man sweats.'

Trump also said Christie’s debate plastering of Rubio earlier that month was ‘one of the greatest prosecutions I’ve ever seen.’

‘I saw Chris take him apart, and honestly I thought he was going to die, Rubio,’ Trump said. ‘He was so scared, like a little frightened puppy.’

That same day, Rubio was also going after Trump on the campaign trail.

Speaking at a rally in Dallas, Rubio read out some of Trump's tweets from that time, which accused the Florida senator of a 'meltdown'.

'Let me tell you something, during the debate last night he went backstage during one of the breaks, two of the breaks - he was having a meltdown,' Rubio told supporters.

'First he had this makeup thing, he was applying makeup around his mustache because he had one of those sweat mustaches.

'Then he asked for a full-length mirror. I don't know why because the podium goes up to here,' Rubio continued, motioning to his chest.

'Maybe to make sure his pants weren't wet?' Rubio suggested.

'I don't know.'
