Data from President Donald Trump's first internal reelection campaign poll conducted in March, obtained exclusively by ABC News, showed him losing a matchup by wide margins to former Vice President Joe Biden in key battleground states.
Trump has repeatedly denied that such data exists.
The polling data, revealed for the first time by ABC News, showed a double-digit lead for Biden in Pennsylvania 55-39 and Wisconsin 51-41 and had Biden leading by seven points in Florida. In Texas, a Republican stronghold, the numbers showed the president only leading by two points.
