Washington — Sen. Scott Brown (R., Mass.) gave a heartfelt introduction to former Massachusetts governor Mitt Romney this afternoon at CPAC. National Review Online caught up with him backstage. He tells us that he’s adjusting well to the Senate and is “keeping in touch regularly” with his new colleagues, including Sen. Harry Reid. Though he has “no idea” about Romney’s presidential ambitions, he says he came to CPAC “simply to support a friend and leader I’ve admired for many years.”
