WASHINGTON — In a victory for President Barack Obama, the Senate passed bipartisan legislation Friday night to strengthen the administration’s hand in global trade talks, clearing the way for a highly unpredictable summer showdown in the House.

The vote was 62-37 to give Obama authority to complete trade deals that Congress could approve or reject, but not change. A total of 48 Republicans supported the measure, but only 14 of the Senate’s 44 Democrats backed a president of their own party on legislation near the top of his second-term agenda.

Obama hailed the vote in a statement that said trade deals “done right” are important to “expanding opportunities for the middle class, leveling the playing field for American workers and establishing rules for the global economy that help our businesses grow and hire.”

Separate legislation to prevent parts of the anti-terror USA Patriot Act from lapsing on June 1 was caught in a post-midnight showdown between a pair of Kentuckians — Majority Leader Mitch McConnell on the one hand, and presidential hopeful Rand Paul on the other.

McConnell favored renewal of a program of bulk telephone collection by the National Security Agency, while Paul was unyielding in opposition. “My filibuster continues to end NSA illegal spying,” he tweeted.
