Since the third Republican Debate on Oct. 28, Republican Presidential candidate and billionaire Donald Trump has been strongly against his conservative counterparts, in particular Florida Senator, Marco Rubio.

“All you have to do is look at his credit card,” Trump recently said about Rubio in an interview.

“He’s a disaster with his credit cards,” he continued. “I’ll tell you what I love, Florida. I am in Florida all the time and for years I’ve been hearing his credit cards are a disaster. I would think that when you take a look at it, you’re going to find that, but his credit card debt and his problems with credit cards and what he did when he was running the party apparatus with credit cards – I’ve heard about it for years. He has a very bad record of finances. If you look at what happened with his houses … he certainly lives above his means. There’s no question about that.”

Marco Rubio’s personal finances aren’t the only things Trump has called into question. Trump went on a tirade on Twitter Sunday morning tweeting out multiple tweets attacking the Senator.

“Anybody that believes in strong borders and stopping illegal immigration cannot vote for Marco Rubio,” Trump tweeted.

‪”@Morning_Joe‬‪: Marco only won the debate in the minds of desperate people. I won every on-line poll, even crazy @CNBC. Marco good looking?‬,” Trump added.‬

“Instead of accusing the Senator of having a weak stance on immigration and making personal attacks about the Senator’s finances, perhaps Donald Trump should be more concerned about explaining his own bankruptcies and flip flops on immigration,” Taylor Boutelle, Director of Communications for UCF Students for Rubio, said. “Marco Rubio has made it clear that the claims made against his credit card debt had been discredited when he ran against Charlie Crist for the US Senate. Senator Rubio also hasn’t hid from the fact that he does have a mortgage, has had student loans, and that his parents were Cuban immigrants. Although Trump clearly has never struggled in the money department, Senator Rubio has the experience in both financial and immigration issues that make him more appealing and relatable to a voting population made up of middle class citizens.”

“I think that Senator Rubio has lived a life that many hardworking Americans can relate to, and that he is doing a great job conveying how his past makes him a great candidate,” Chairman UCF Students for Rubio Amber Mariano added.

“When Donald comes across a poll he doesn’t like, he gets weird and he does these sorts of strange things and that’s fine – that’s the sort of campaign he wants to run and he’s entitled to it…I’m going to continue to talk about the future of America… I can’t respond to everything he says, I wouldn’t be able to run a campaign,” Macro Rubio said at a press conference last week.
