Gary Cohn, the former head of the National Economic Council and key advisor to President Donald Trump, said personal tax cuts need to be made permanent.
In his first interview since exiting the White House, Cohn said that is the one piece of unfinished business he left behind. Cohn announced his resignation in March and left in early April.
"The one thing that we regret not having been able to do in the original tax bill was the personal side expired. We would like to go back and make the personal side permanent," Cohn told CNBC's Bib Pisani in a "Squawk on the Street" interview. "We do not want that to expire."
The original tax bill, which Congress passed in December, slashed corporate taxes from 35 percent to 21 percent and reduced tax rates for millions of Americans. It also doubled the standard deduction.
