Lt. Gov. Anthony Brown pledged Wednesday to cap rising tuition costs at Maryland's colleges if he is elected governor. 

Brown, a Democrat, vowed in a statement he would limit annual tuition increases to 3 percent. To keep that promise, Brown said he would use state tax dollars to offset any other rising costs at colleges. He did not specify 

The University of Maryland's Board of Regents sets tuition rates at the state's colleges, although the amount of the increase is usually impacted by how much money the state government allocates for higher education. 

This year, for instance, Gov. Martin O'Malley budgeted an extra $10 million for higher education so that tuition would rise by only 3 percent instead of 5 percent.

Brown faces Attorney General Douglas F. Gansler and Del. Heather Mizeur of Montgomery County in the June 24 primary election.
