Senate Minority Leader Chuck Schumer (D-N.Y.) told President Donald Trump this week that there will be no deal on Dreamers if hard-line conservative GOP Sen. Tom Cotton is involved, according to several congressional sources.

Schumer also told the president that he was not being well-served by White House staffers during negotiations over the fate of 700,000 young immigrants who face potential deportation if no deal is reached to protect them.

Trump grew defensive during the private exchange, which took place as both men were attending the Congressional Gold Medal event for former Senate Majority Leader Bob Dole (R-Kan.) in the Capitol on Wednesday, the sources said.
