House Speaker Paul Ryan emerged from a last-minute White House meeting Thursday between President Donald Trump and House Republicans to say that the president told them he will refuse to sign a stopgap funding bill as its currently written a measure that would avert a shutdown before a Friday midnight deadline.
Ryan told reporters that he and other GOP leaders were going back inside to try to add more on border security to the legislation.
Trump had called the meeting on short notice amid criticism that he was softening on a key campaign promise.
