WASHINGTON, Jan 22 (Reuters) - The Senate Commerce

Committee said on Wednesday it will hold a Jan. 29 hearing on

President Donald Trump's nominee to lead the Commerce

Department, the agency that has become a key U.S. tool in its

efforts to constrain China's tech sector.

Trump tapped Wall Street CEO Howard Lutnick to lead the

department and his trade and tariff strategy.

Lutnick, the head of brokerage firm Cantor Fitzgerald, will

also have "additional direct responsibility" for the U.S. Trade

Representative's office.

Lutnick also runs brokerage BGC Group ( BGC ) and is

chairman of Newmark Group, a commercial real estate services

firm, and FMX, a platform owned by some of Wall Street's biggest

banks and traders.
