But President Trump is already making an effort to ensure the lingering questions over her claims of Native American heritage - and her attempt to substantiate them - will follow her to the first caucus state.
Warren has been an emerging national figure for more than a decade as an advocate for consumer protection, now a senator and a regular target of President Donald Trump. "I wish I could just open the door and have lots of folks in, but this is a way to do it", she said, adding that her beer of choice is Michelob Ultra, what she called "the club soda of beers".
Warren also defended her decision to host a live Instagram event on New Year's Eve from the kitchen of her home in Cambridge, Massachusetts.
"We're now in the 13th day of the shutdown, we have hundreds of thousands of federal employees not getting their paychecks and work that's not being done all around this country", she said.

But this weekend's trip will be her first swing through Iowa since she stumped for a Senate candidate there in 2014 - making her a latecomer to the state following visits by possible presidential candidates including Kamala Harris, Amy Klobuchar, and a particularly buzzy speech by Cory Booker last fall.
Elizabeth Warren kicked off a 3-day tour of Iowa on a mission to fight. Bernie Sanders during his presidential run in 2016 - or hamper it.
