Massachusetts Senate candidate Elizabeth Warren turns 63 today, and among her birthday gifts is one she probably won't appreciate very much. She's in a tight race against the GOP incumbent, Scott Brown. The state's Republican party announced this morning that it is gifting Warren, a Harvard Law professor, with a complimentary account at ancestry.com.

"Since Professor Warren has failed to come up with any evidence supporting her claims to Native American ancestry, we thought this Ancestry.com account would make the perfect birthday gift," said Massachusetts Republican Party executive director Nate Little in a statement.

Warren has come under fire in recent months for identifying herself as Native American in law school directories based on a blood line that she said goes far back, though there has not yet been primary documentation to back up her claim.

The Warren campaign did not immediately respond to ABC News's request for comment.

Scott Brown's birthday falls in September. Watch to see if the state Democrats will follow the Republicans' lead and gift the Senator with a Royalancestry.net account, after the Senator's kings and queens gaffe earlier this week.
