Gov. Patrick's BFF arrives for a fundraiser.

President Barack Obama flies to Boston on Friday to tour a research laboratory at the Massachusetts Institute of Technology.

The lab is working on cutting-edge clean energy technology.

The president then delivers remarks at MIT challenging Americans to lead the global economy in clean energy and to highlight Recovery Act investments that the White House says are creating jobs and making advancements in wind energy.

While in Boston, he'll also attend fundraisers for Massachusetts Gov. Deval Patrick.
