President Donald Trump rejected the latest attempt by Senate Republicans to reopen the Department of Homeland Security, dismissing a plan that would fund Immigration and Customs Enforcement at a later date.

White House aides briefed the president on the plan Sunday, according to two sources familiar with the matter, as Democrats demand new guardrails on immigration enforcement in exchange for DHS funding. Senate Majority Leader John Thune (R-SD) then spoke with Trump by phone but was rebuffed.
