NEW ORLEANS (AP) — Louisiana’s U.S. senators added hundreds of millions of dollars in pet projects to the $410 billion spending bill awaiting President Barack Obama’s signature, ranking them near the top of the list of lawmakers who placed so-called “earmarks” in the measure, according to a nonpartisan watchdog group. Sen. Mary Landrieu, a Democrat, ranked second with more than $332 million worth of earmarks in the bill, according to the analysis from Taxpayers for Common Sense.
