EXCLUSIVE: Marco Rubio Moves Toward 2016 Presidential Bid

— -- Sen. Marco Rubio has begun taking concrete steps toward launching a presidential bid, asking his top advisors to prepare for a campaign, signing on a leading Republican fundraiser, and planning extensive travel to early-voting states in the coming weeks, ABC News has learned.

"He has told us to proceed as if he is running for president," a senior Rubio advisor tells ABC News.

Leading the effort to raise the $50 million or more he’ll need to run in the Republican primaries will be Anna Rogers, currently the finance director for American Crossroads, the conservative group started by Karl Rove that raised more than $200 million to help elect Republicans over the past two elections.

Rogers will begin working at Rubio’s political action committee on February 1 and would become the finance director of Rubio’s presidential campaign.

Rubio, 43, will gather on Friday and Saturday at the Delano Hotel in Miami with 300 supporters and major donors to his Reclaim America PAC to discuss his political future.

Aides expect Rubio will make a final decision in the comings weeks, but his schedule for the next month already looks more like the schedule of a presidential candidate than a senator.

ABC News has learned Rubio plans to skip all votes in the Senate next week and instead take a campaign fundraising swing through California with events in Beverly Hills, Newport Beach, Rancho Sante Fe and Costa Mesa. He also plans fundraising stops in Texas and Chicago.

Rubio has also scheduled a book tour that will take him to all the early primary states. A senior aide to the Florida senator tells ABC News Rubio’s book tour will include stops in Iowa, New Hampshire, South Carolina, Florida and Nevada. The first stop is tentatively scheduled for February 13 in Des Moines.
