With one day down and three days to go, the first real clues about how the Republican National Convention will unfold were seen with the surprising chaos over the roll call vote.
While this is expected to be a week filled with the unexpected, one particularly unusual move came when Donald Trump decided to call into a news program while his own convention was underway. He also gave a hint of what his capstone speech will be like on Thursday night after introducing his wife Melania.
But even more surprises are in store for today.
Here are five key storylines to keep an eye on:
T
he vote to adopt the convention rules proved to be the most controversial moment in the convention so far, when the final members of the Never-Trump movement were thwarted on the convention floor.
The floor vote was the last remaining hope for those who wanted the Republican Party to nominate someone other than Trump and their fate was sealed by some procedural wrangling last week.
Ultimately, the pro-Trump forces and the very establishment he once openly criticized joined forces -- some to save Trump, some to preserve the integrity of the voting process that made Trump the presumptive nominee.
It was an ugly start to the convention, and suggestive of how Trump may not have control of his own convention.
T
here's a chance for a different kind of floor fight today as the delegations are going to go state-by-state as part of the roll call.
Even though the result is preordained, there's still an opportunity for delegates to vent and go against the grain when given their time at the mic.
Considering today's theme is "Make America Work Again," it will be particularly interesting to see how everything works inside the Quicken Loans Arena.
T
wo of Trump's former rivals -- New Jersey Gov. Chris Christie and Dr. Ben Carson -- will both be speaking on his behalf this evening, which is something that their supporters are likely looking forward to.
Their inclusion in the lineup should come as little surprise since they both endorsed Trump shortly after dropping out themselves and have regularly touted his achievements on the campaign trail.
And as for Christie, this won't be the first time he's addressing a convention either. Christie was given a prime speaking slot at Mitt Romney's convention in 2012, which many took issue with at the time since he appeared to speak more about himself than Romney. It'll be worth seeing if history repeats itself again this year.
W
hile Melania Trump's speech Monday night was definitely a rarity since the potential first lady shies away from the spotlight, an even more unique occurrence is on the docket tonight.
Tiffany Trump, the real estate magnate's 22-year-old daughter from his second marriage to Marla Maples, has never given a speech on the campaign trail. Thus far, that's made sense since she only just graduated from her father's alma mater in May.
But beyond speeches, she has really only appeared at two or three events where all of her older siblings were also involved -- including her father's presidential announcement -- and rarely gives interviews, making tonight's speech an even more special event.
Her older brother Donald Jr. will also take the stage in Cleveland tonight, but his inclusion comes as less of a shock since he has been an active presence during his father's campaign.
O
n a more political note, Speaker of the House Paul Ryan is also going to be taking the stage tonight and he's expected to do something of a tightrope act.
Ryan did endorse Trump after it became clear that Trump was the party's presumptive nominee, but he hasn't hesitated to criticize Trump since then.
Rather than dedicate his speech to solely praising Trump, Ryan is expected to focus his speech to discussing the House Republicans' agenda.
