All eyes will be on U.S. Sen. Marco Rubio, R-Fla., on Monday as the Republican senator with Cuban roots will declare whether or not he will run for president in 2016.

His announcement is timed one day after former Secretary of State and U.S. Senator from New York Hillary Clinton announced that she would be running for the presidency.

Rubio, who has been a Florida senator since 2011, has been widely expected to declare his candidacy for the GOP nomination for president for months and has been looked to for years as one of the GOP's rising young stars. His position in the key battleground state of Florida and his Cuban heritage -- which has been seen as giving him inroads with the key Latino voting demographic -- have long made him an attractive prospect for president among the GOP fan base.

In perhaps a precursor of what people can expect from Rubio on Monday, the senator released a video late last week, titled "Marco Rubio: A New American Century," giving is supporters a snapshot of what he would be saying during his announcement.

The first 40 seconds of the video highlights Rubio's connection to Cuba through several soundbites:

"I've been raised in a community of exiles, of people who lost their country, of people who know what it's like to live somewhere else," Rubio said during Election Night in 2010.

"For me, America isn't just a country, it's a place that literally changed the history of my family. It's a nation of equal opportunity it's the most powerful force for good that the world has ever known. This is the America that welcomed my parents," said the senator during the Conservative Political Action Conference in February.

"And so now I know that every chance I have ever had and everything that I will ever accomplish, I owe to God, to my parents' sacrifices and to the United States of America."

The rest of the video shows Rubio blasting the Obama administration on its financial policies, Obamacare health care plan and foreign policy, among others, while finishing off with soundbites outlining, in no specific terms, his vision for the nation.

News broke earlier this week that a previously unknown Super PAC, Conservative Solutions PAC, would be backing Rubio. A Super PAC is an independent group which can raise unlimited money from individuals, unions and corporation to advocate for or against political candidates as long as they don't contribute directly to a candidate or party.

A day before Clinton announced her presidential candidacy, Rubio during an interview with the conservative-leaning publication Breibart News blasted Clinton's tenure as Secretary of State, calling her the "architect of failed foreign policy," while calling President Obama's reported consideration of taking Cuba off the State Department's list of State Sponsors of Terrorism "ridiculous."

President Obama met up with and shook hands with Cuba's President Raul Castro this weekend while Obama was attending the Summit of the Americas in Panama.

Rubio, who has been open about his criticism of President Obama's December announcement that the U.S. would engage politically with Cuba, pointed out in the Breibart interview that Cuba was "harboring the fugitives of American justice, including the killer of an American police officer, and dozens of people who have stolen millions of dollars from Medicare -- fraud from the American taxpayer."
