Senate Republican leaders are expected to abandon a proposal for $1 billion in security money for the White House complex and President Donald Trump’s ballroom after it has failed to win enough party support on Capitol Hill. The White House has pressured Republicans to try to add the money to a roughly $70 billion bill intended to restore funding to U.S. Immigration and Customs Enforcement and the Border Patrol. But some Republicans are questioning the security price tag and asking for more detail from the White House and U.S. Secret Service about how the money would be used.
