Brown, 57, burst onto the national stage in 2010 when he unexpectedly won a special Senate election to fill the seat left vacant by the death of Sen. Edward M. Kennedy (D-Mass.). He was defeated in 2012 by now-Sen. Elizabeth Warren (D-Mass.).
Brown subsequently moved to New Hampshire, where he unsuccessfully challenged Sen. Jeanne Shaheen (D-N.H.).
Brown has a colorful past, including working as a model — something the New Zealand Herald seized upon in a recent story about rumors of Trump tapping him for the post.
“Man tipped for US ambassador role in NZ a former nude model who supports waterboarding,” a headline in the publication said.
Brown's position requires Senate confirmation.
