April 7 (Reuters) - Wall Street's main indexes fell back

into the red in choppy trade on Monday after CNBC reported White

House officials were not aware of U.S. President Donald Trump

considering a 90-day pause in tariffs for all countries except

China.

The White House denial came after stocks rose on a CNBC

report about Trump considering a tariff pause.

CNBC did not immediately respond to a Reuters request for

comment.

At 10:39 a.m. the Dow Jones Industrial Average fell

996.97 points, or 2.60%, to 37,317.89, the S&P 500 lost

115.21 points, or 2.27%, to 4,958.87, and the Nasdaq Composite

lost 320.20 points, or 2.06%, to 15,266.70.
