Friday's a big day for Patch! Throughout Massachusetts, readers will get a chance to hear from U.S. Senate candidate Elizabeth Warren on Friday afternoon, and here in Marlborough, and we're getting a chance to talk with Congresswoman Niki Tsongas as well.

You ask, she answers. Simple as that.

We'll be live with Niki from 9:30 to 10:30 a.m., and if you can't make it then, leave us your questions in the comments and we'll try to get as many unique questions to the Congresswoman during the chat.
