President Trump took to Twitter Thursday to announce a new member of his team.

“Larry Kudlow will be my Chief Economic Advisor as Director of the National Economic Council. Our Country will have many years of Great Economic & Financial Success, with low taxes, unparalleled innovation, fair trade and an ever expanding labor force leading the way! ,” tweeted Trump.

Kudlow is widely known for his now retired cable news program “The Kudlow Report” which aired on CNBC.

In the mid-1990s, Kudlow left his position at Bear Stearns and entered a twelve-step program in order to deal with his addictions to cocaine and alcohol.

In 1970, while he was still a Democrat, Kudlow joined Joseph Duffey’s “New Politics” senatorial campaign in Connecticut. Duffey was a leading anti-war politician during the Vietnam war era. Kudlow, working with Yale University student Bill Clinton as well as many other rising young Democratic students, was known as a “brilliant” district coordinator.

Kudlow worked on the U.S. Senate campaign of Joseph Duffey, along with Bill Clinton, John Podesta, and Michael Medved, another future conservative, and in 1976, he worked on the U.S. Senate campaign of Daniel Patrick Moynihan, along with Tim Russert, against Conservative Party incumbent James L. Buckley, brother of William F. Buckley, Jr.

Kudlow began his career as a staff economist at the Federal Reserve Bank of New York, taking a position “as a junior economist in a job where a master’s degree wasn’t required.” He worked in the division of the Fed that handled open market operations.

During the first term of the Reagan administration (1981–1985), Kudlow was associate director for economics and planning in the Office of Management and Budget (OMB), a part of the Executive Office of the President. While he worked at the OMB, Kudlow was also an advisory committee member of the Federal Home Loan Mortgage Corporation, more commonly known as Freddie Mac.[citation needed] In April 2005, New York Governor George Pataki included Kudlow in a six-member state tax commission.

In February 2009, rumors surfaced that Kudlow was considering a run for U.S. Senator from Connecticut in 2010 against Christopher Dodd. However, on March 24, 2009, he announced on his program that he was not running.

In January 2010, after the victory of Scott Brown for the Senate seat from Massachusetts, a movement began in Buffalo, New York to draft Kudlow for the U.S. Senate seat in currently held by Charles Schumer. On January 29, 2010, Kudlow said that he was considering entering the race: “I do believe that retiring Sen. Schumer would be a noble cause.” Kudlow never made any mention of the race again, allowing Gary Berntsen and Jay Townsend to pursue the seat instead.

Kudlow could have run for the Senate from either Connecticut or New York in 2016.

In October 2015, U.S. Senator Richard Blumenthal, in an email to supporters, attacked Kudlow as “a champion of big corporations and big money” despite Kudlow’s not announcing a run.
