Is there a bus that can take me from near the mall in Columbia MD to a MARC station that goes to/from DC daily?

I have an internship literally at the capitol in Washington DC this summer and I normally would drive to the MARC station in Dorsey and ride to union station then just walk to work. But my car is out of commission, and was wondering if there is a bus that goes near the mall in Columbia to a MARC station that can get me to DC mon-fri.
