BOSTON (AP) — Since winning last year's grueling campaign, U.S. Sen. Elizabeth Warren has kept a relatively low profile in Massachusetts.

On Monday, the Democrat is scheduled to give one of her first major addresses since defeating former Republican U.S. Sen. Scott Brown when she appears before a breakfast meeting of the New England Council. About 300 local business leaders are expected to attend.

Warren's election and the resignation of longtime U.S. Sen. John Kerry to become secretary of state propelled Warren into the position of senior senator for Massachusetts just a month after being sworn in.

One of Warren's priorities since taking office has been protecting the federal Consumer Financial Protection Bureau, which she helped create.

Warren has called on Republicans to lift their opposition to President Obama's choice to lead the bureau.
