CLEVELAND — Ted Cruz took the stage Wednesday to huge cheers at the Republican National Convention — and left amid a chorus of boos after refusing to endorse Donald Trump.

Cruz built to a crescendo, getting big cheers from the mix of Trump and Cruz delegates in the Quicken Loans Arena packed for the first time of the convention as he sounded like he might be on the verge of throwing his support behind a man he once bear-hugged before a bitter rejection at the end of a vicious primary season.

“To those listening, please don’t stay home in November,” he said as the crowd rose in celebration of what many thought was going to be a late-coming endorsement that could help Trump with conservative holdouts.

Cruz’s next line brought them crashing down on him.

“Vote your conscience,” he said.

The crowd viscerally turned on him, chanting, “Trump, Trump, Trump!”

“Endorse Trump! Endorse Trump!” a woman in a “Make America Great Again” hat who’d been enthusiastically cheering Cruz kept screaming at him.

Jimmy Fallon didn't pass up a yuuuuge opportunity to mock Donald Trump.

"The Tonight Show" host recreated Trumps' over-the-top entrance at Monday's Republican National Convention, making sure to take a jab at his wife Melania's allegedly plagiarized speech during Tuesday's opening sketch.

"Did you see Melania, she stole the show … literally," Fallon said. "I mean, she delivered her speech like a true first lady. That first lady being Michelle Obama, but still. She might have plagiarized some of it but you got to admit she did it harder, better, faster, stronger, and you can quote me on that."

Hillary Clinton ha servido como secretaria de Estado, senadora de los Estados Unidos por el estado de Nueva York, primera dama de los Estados Unidos, primera dama del estado de Arkansas, abogada, profesora de leyes y activista. Pero lo primero que dirán sus amigos y su familia es que ella nunca ha olvidado de dónde viene ni por quiénes ha luchado durante su vida.

Después de servir como abogada para el comité del Congreso encargado de investigar al presidente Nixon, Hillary se mudó a Arkansas donde enseñó derecho penal, procedimiento penal y abogacía de litigación y dirigió el consultorio de asistencia jurídica y proyectos en las prisiones.

Amid all the controversy surrounding Melania Trump’s speech at the Republican National Convention on Monday night which ripped off a speech given by Michelle Obama eight years earlier, it turns out Melania also plagiarized the lyrics from a pop song from the 1980s – and it wasn’t just any song. If you’ve ever been Rickrolled, which is to say you’ve been the victim of someone who slipped you a link to Rick Astley’s “Never Gonna Give You Up” video, it turns out Melania Trump just Rickrolled the entire nation.

In a development almost too bizarre for words, Twitter users have picked up on the fact that Melania Trump’s speech included the phrase “He will never, ever give up. And most importantly, he will never, ever let you down.” This is a rather blatant ripoff of Astley’s signature lyrics “Never gonna give you up, never gonna let you down.”

It’s not immediately clear whether Melania knowingly inserted the “Never Gonna Give You Up” lyrics into her speech on purpose as a way of intentionally Rickrolling the nation, or if a speechwriter slipped these words into her speech as a way of trying to make her look foolish. In light of the larger picture in which so much of the speech was stolen from Michelle Obama, it’s fair to ask the question of whether a rogue speechwriter was trying multiple avenues of embarrassing Melania in the same speech. In any case, it caused Rick Astley’s name to briefly become a trending topic on Twitter.
