The brother of White House Chief of Staff-designate Rahm Emanuel will also serve in the Obama administration. But it will be the bioethicist Emanuel joining his brother and not the fast-talking Hollywood agent Emanuel, who inspired the character "Ari" on the HBO hit "Entourage."

Ezekiel Emanuel, a bioethicist at the National Institutes of Health, will serve in the White House Office of Management and Budget (OMB) as a counselor on health policy.

Emanuel will work with Health and Human Services Secretary-designate Tom Daschle to formulate national health insurance policy, the Wall Street Journal reported.

A M.D./PhD from Harvard University, Ezekiel Emanuel is the eldest of the three Emanuel brothers. So far, President-elect Obama has yet to enlist Ari Emanuel, the now-famous Hollywood agent whom the character of Ari Gold on HBO's "Entourage" was based.
