(CNN) - Elizabeth Warren, who is the acting head of the Consumer Financial Protection Bureau, is considering a Senate run in Massachusetts against incumbent Republican Sen. Scott Brown.
Officials within the Democratic Party are urging the Massachusetts native and Harvard law professor to take the plunge in hopes she could oust Brown with her own following, ties to the state and political drive.
However, multiple Democratic sources tell CNN that Warren would prefer a recess appointment to run the bureau over a Senate run, action that appears unlikely given some senators have said they would block any nominee for the agency charged with making consumer financial products and services – including applying for mortgages and credit cards – work for Americans.
Some inside the White House would rather she run for office than face the uncertainty of a recess appointment, but said she has avoided discussing the matter openly for fear of polarizing the bureau.
"She is actively considering a run but wants to make sure that the bureau is up, operational and set for success," one Democratic official said.
The sense among Democrats who want her to run is that she could transform the race with her national profile, while raising money across the country.
But senior CFPB spokesman Jen Howard told CNN, "Elizabeth Warren is 100 percent focused on building the new consumer agency."
Warren became a somewhat polarizing figure for her role as chair of the Congressional Oversight Panel created to investigate the U.S. banking bailout following the financial crisis.
The Bureau was created as part of the controversial Dodd-Frank Act passed through Congress, largely along party lines, in July 2010. The bill set up regulations to implement financial safeguards and increase consumer protections and has received criticism from conservatives critical of government intervention.
Brown won a special election to fill the seat vacated by former Sen. Ted Kennedy in 2009 and has since faced criticism from some on the left who hope to recapture the seat in the historically Democratic-leaning state that President Barack Obama won by 20 points in the 2008 presidential election.
Brown has attempted to navigate between the demands of the right and many of his constituent's more liberal ideology. Most recently he announced his opposition to fellow Republican Rep. Paul Ryan's controversial plan to overhaul the Medicare health care program for seniors.
