Congress has until the end of the week to send the bill to Trump's desk, but the path forward for the rescissions package remains a bit murky.

Senate GOP leaders are looking to avoid a repeat of the lengthy and sometimes bewildering floor process that led to the passage of the Trump tax bill by locking down key details with holdouts before the chamber moves to a vote-a-rama Wednesday on a bill to claw back funding.

The package, which narrowly passed the House in May, would cull back funding from Public Broadcasting Service and National Public Radio.
