A major showdown is unfolding in Washington as Senate Republicans push back against a controversial $1.776 billion settlement fund tied to President Donald Trump. The dispute has already stalled a key Homeland Security spending bill and exposed growing tensions between the White House and members of Trump's own party.

Republican senators have privately told White House aides they think the fund should be scrapped

Democrats have branded the fund a "slush fund" and are vowing to block its implementation, further complicating efforts to pass vital Homeland Security spending legislation
