The agency's authorization expired on June 30, halting all new loan guarantees and other assistance to foreign customers seeking to purchase goods from American companies. The agency continues to service existing loans.  A clear majority in the House supports resurrecting the agency, but it will be up to House leaders to decide whether the chamber will get a vote, or whether to allow the bank's powerful opponents — led by the House majority leader, the majority whip, the Ways and Means Committee chairman and the Financial Services Committee chairman — to stand in the way.

Influential conservatives like Charles and David Koch and the Club for Growth political action committee have made opposition to the bank, known as Ex-Im, a litmus test for their financial support, persuading all but one Republican presidential candidate, Senator Lindsey Graham of South Carolina, to advocate the bank's demise.  But Sunday's session showed that the U.S. Chamber of Commerce and National Association of Manufacturers still hold some sway in a Republican Party increasingly willing to buck business lobbies.  "With more than 60 export credit agencies enabling our foreign competitors to seize opportunities away from workers, it's critical that Congress restores this important tool for American exports," Jay Timmons, the president of the manufacturers' association, said on Sunday.  The Sunday session to hasten action on the highway bill, called by Senator Mitch McConnell of Kentucky, the majority leader, came as tensions rose between Republican leaders and rank-and-file conservatives, intensified by the presidential candidacies of four Republican senators — Ted Cruz of Texas, Rand Paul of Kentucky, Marco Rubio of Florida and Mr. Graham.  On Friday, after Mr. McConnell scheduled the Ex-Im vote, Mr. Cruz took to the Senate floor to say that Mr. McConnell had assured him that he had made no deal to bring the bank to a vote.  "Not only what he told every Republican senator, but what he told the press over and over and over again was a simple lie," Mr. Cruz said.

"Squabbling and sanctimony may be tolerated on the campaign trail, but not in here," said Senator Orrin G. Hatch of Utah, the most senior Republican. "We are not here on some frolic or to pursue personal ambitions. We are here because the people of the United States have entrusted us with the solemn responsibility to act on their behalf."  "It is a sacred trust in which pettiness or grandstanding should have no part," he added.  Unrepentant, Mr. Cruz responded, "It is entirely consistent with decorum and with the nature of this body traditionally as the world's greatest deliberative body to speak the truth."
In a rare and fiery weekend session, the Senate voted to resurrect the Export-Import Bank, handing GOP conservatives a major defeat. The NYT reports.
