April 18 (Reuters) - U.S. stocks were on track to open slightly lower on Tuesday as investors weighed quarterly earnings and a possible delay in tax reforms, while keeping an eye on global politics.
U.S. Treasury Secretary Steven Mnuchin told the Financial Times on Monday that the Trump administration's timetable for tax reform was probably delayed following setbacks in negotiations with Congress over healthcare.
Mnuchin's statement added to concerns about President Donald Trump's ability to deliver on his promises to cut taxes and simplify regulations - bets on which U.S. stocks have hit record highs since his election.

Shares of Morgan Stanley, Wells Fargo and JPMorgan were trading lower.
