WASHINGTON (AP) - Congress has reached the homestretch on a major overhaul of federal transportation programs that is critical if the nation is to avoid steep cutbacks in highway and transit aid.
The bill is driven partly by election-year politics. Both Congress and President Barack Obama have made transportation infrastructure investment the centerpiece of their jobs agendas.
But the political imperative for passing a bill has been complicated by House Republicans' insistence on including a mandate for federal approval of the Keystone XL oil pipeline. The White House has threatened to veto the measure if it retains the Keystone provision.
