Likely GOP presidential candidate Tim Pawlenty next month on tax day will headline a Tea Party rally in Boston.

The former Minnesota governor is set to deliver an address at the event, organized by the Greater Boston Tea Party. 

Pawlenty's appearance allows him to appeal to the conservative Tea Party movement, which played a crucial role in the 2010 midterm elections, when Republicans made gains in the House and Senate.

It also places him on the home turf of former Massachusetts Gov. Mitt Romney (R), a probable presidential candidate who many observers say is the early front runner in the GOP primary field.

On Wednesday, Pawlenty is appearing in Cleveland to give a speech on the economy in the crucial swing state.
