LaHood said Boehner "doesn't want to pass a bill with Democrats because that would be embarrassing to him.
"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 House had been scheduled to try a third attempt Wednesday to pass a short-term highway extension, but the measure is listed as postponed on the most recent calendar released by House Majority Leader Eric Cantor's (R-Va.) office.
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.
