Donald Trump’s new economic adviser has a history of slamming the President on Twitter.

Conservative commentator Larry Kudlow served as an informal economic adviser to Mr Trump’s 2016 campaign after the real estate tycoon’s ascension in the race. But prior to that, in 2015, he often made jabs at the then-candidate through social media.

Mr Kudlow shared many articles attacking Mr Trump, including one criticising his immigration policy and a piece by Jonah Goldberg in the conservative National Review titled, “No Movement That Embraces Trump Can Call Itself Conservative”.

One post that Mr Kudlow retweeted featured a video of Mr Trump being body slammed during a WWE appearance by a wrestler with an image of Jeb Bush edited over his face.

Now, the former budget aide to Ronald Reagan will help craft Mr Trump’s policies on taxes and trade as part of the White House staff.

“Larry Kudlow was offered, and accepted, the position of assistant to the President for Economic Policy and Director of the National Economic Council,” said White House Press Secretary Sarah Huckabee Sanders. “We will work to have an orderly transition and will keep everyone posted on the timing of him officially assuming the role.”

Mr Kudlow will become Mr Trump’s second top economic adviser. The President’s first, former Goldman Sachs president Gary Cohn, resigned last week after a reported disagreement over Mr Trump’s plan to impose sweeping tariffs on steel and aluminium imports.

But the selection of Mr Kudlow, however, does nothing to solve the Trump administration’s internal dispute over tariffs.

In an op-ed for CNBC earlier this month, Mr Kudlow laid out why he disagreed with Mr Trump’s plan.

“Steel and aluminum may win in the short term, but steel and aluminum users and consumers will lose,” Mr Kudlow wrote. “In fact, tariff hikes are really tax hikes.”

Before the announcement that Mr Kudlow had been chosen, Mr Trump acknowledged that he and the analyst disagreed over tariffs. But the President said he welcomed the difference of opinion.

“I’m looking at Larry Kudlow very strongly,” Mr Trump told reporters. “I’ve known him a long time. We don’t agree on everything but in this case I think that’s good. I want to have a divergent opinion – we agree on most.”

He added that Mr Kudlow has “come around to believing in tariffs as a negotiating point.”
