President Donald Trump is leaning toward preserving atrillion-dollar tax break for corporate borrowers — a move thateconomists say could jeopardize his goal of robust economicgrowth.

The administration's “preference” is to keep so-called interestdeductibility, which allows companies to subtract interest paymentsfrom taxable income, Treasury Secretary Steven Mnuchin told TheEconomist in a joint interview with Trump. Their remarks, publishedThursday, reveal a new fissure between Trump's vision for taxpolicy and that offered by House Speaker Paul Ryan.

Ryan has called for eliminating interest deductibility, a movethat would raise an estimated $1 trillion over 10 years. Gainingthat revenue would help pay for rate cuts and other tax measuresthat Ryan and other GOP leaders want, including a provision thatwould allow corporations to immediately write off the cost of theircapital spending.
