LaHood: Boehner needs to 'show a little leadership' on highway bill

The current funding for transportation is set to run out on March 31. The Senate has passed a $109 billion bill that would provide transportation funding for the next two years, but the House has struggled this week to approve a short-term extension of the current funding.

"And he can't pass it as long as he's got these 40-50 intransigent conservatives who do not want to do anything," LaHood said of Boehner's plan to rely on Republican votes to pass the transportation measure.

The previous attempts on Monday and Tuesday to pass a 90-day and 60-day extension, respectively, were pulled after it appeared GOP leaders did not have the required two-thirds vote to consider the measure under a suspension of the House rules.

If lawmakers do not extend the highway legislation by the end of the week, the federal government will be unable to collect the federal gas tax that is normally used to fund transportation projects.
