and later:

President Trump on Thursday appeared bewildered by his own administration's goals, tweeting out his disapproval of a House bill reauthorizing the Foreign Intelligence Surveillance Act (FISA) — a contradiction of the White House's official position — before tacking his support back onto it an hour and a half later.

As Jonathan Chait observed at New York, Trump's initial tweet was apparently a response to Fox News judicial analyst Andrew Napolitano, who advised Trump on TV against the reauthorization of the bill. "The president's alarm was unfortunate, since the Trump administration strongly supports reauthorization of this law," Chait writes. "It has sent its highest-ranking security officials to lobby Congress for reauthorization, and reiterated its endorsement of the law as recently as last night."
The House passed re-authorization of FISA today. Rand Paul vowed to fight in in the Senate.

Paul readies fight in Senate

Shortly after the House vote on the amendment, Sen. Rand Paul, a Kentucky Republican known for libertarian stances on surveillance issues, reiterated his threat to filibuster the bill on the Senate side.

"No American should have their right to privacy taken away! #FILIBUSTER" he tweeted.

Paul has been leading an effort, alongside Sen. Ron Wyden, an Oregon Democrat, for his own amendment in the Senate, which has a little over a dozen senators from both parties as co-sponsors.

Ahead of the House vote Thursday morning, other senators were largely in favor of reauthorization, though some acknowledged there was debate over whether it should be reformed.
