U.S. Sen. Marco Rubio, R-Fla., joined a host of conservative senators, including two rivals for the Republican presidential nomination, in writing Fred Hochberg, the chairman and president of the Export-Import Bank, about plans for an “orderly liquidation” of the Export-Import Bank. Other senators who signed on to the letter were Republican U.S. Sens. Ted Cruz of Texas, Mike Lee of Utah, Rand Paul of Kentucky, Ben Sasse of Nebraska and Pat Toomey of Pennsylvania. Cruz and Paul, like Rubio, are running for their party’s presidential nomination in 2016.
