The announcement comes ahead of Trump's planned economic policy speech in Detroit on Monday. Trump is slated to detail personal and corporate tax cuts as well as energy and health-care policy changes aimed to boost American economic growth.
"It's going to be a very substantial pro-growth message," Larry Kudlow, a senior CNBC contributor and informal adviser to the Trump campaign, said Thursday.
The policy team announcement and economic speech come as the Trump campaign tries to refocus its message after a tumultuous week. Trump has sagged in recent polls against Democratic nominee Hillary Clinton, and more headlines have focused on his antics than his policies.
In recent days, Trump has declined to endorse GOP House Speaker Paul Ryan for re-election and clashed with the parents of a fallen Muslim-American soldier. Meanwhile, more prominent Republicans have said they will not vote for him.
An economic policy focus would mark a welcome shift for the Trump campaign. The billionaire developer has repeatedly highlight his business acumen in pitches to voters, but given an inconsistent picture of his policy in public appearances.
