Larry Kudlow

WASHINGTON — President Donald Trump has chosen Larry Kudlow to be his top economic aide, elevating the influence of a longtime fixture on the CNBC business news network who previously served in the Reagan administration and has emerged as a leading evangelist for tax cuts and a smaller government.

Kudlow told The Associated Press on Wednesday that he has accepted the offer, saying the U.S. economy is poised to take off after Trump signed $1.5 trillion worth of tax cuts into law.

“The economy is starting to roar and we’re going to get more of that,” he said.

Kudlow will join an administration in the middle of a tumultuous remodeling as a wave of White House staffers and top officials have departed in recent weeks. Trump on Tuesday dumped via Twitter his secretary of state, former Exxon Mobil CEO Rex Tillerson.

The famously pinstripe-suited Kudlow would succeed Gary Cohn, a former Goldman Sachs executive who is leaving the post in a dispute over Trump’s decision to impose tariffs on imported steel and aluminum.

With Trump’s tax cuts already being implemented, Kudlow would be advising a president who appears increasingly determined to tax imports — a policy that Kudlow personally opposes. Kudlow said that he is “in accord” with Trump’s agenda and that his team at the White House would help implement the policies set by the president.

Trump has promised to reduce the trade imbalance with China and rewrite the North American Free Trade Agreement with Canada and Mexico. Kudlow declined to say what advice he would give the president on trade issues, saying, instead that Trump is “a very good negotiator.”

Kudlow, 70, has informally advised the Trump administration in the past and he has spoken with the president “at some length in recent days,” so that he is ready “to hit the ground running.”

Friends and colleagues say Kudlow possesses two critical attributes prized by the president: He is a bluntly spoken debater and is resolutely loyal.

“He’s a very sensitive man and a very logical man, which is exactly what Trump needs,” said Arthur Laffer, a well-known economist and longtime friend of Kudlow.
