At The Hill by By Cristina Marcos, Jordain Carney--
The Senate is poised to make history this week with Vice President Mike Pence expected to have to break a tie on a Cabinet nominee.
Senators are scheduled to take a final vote Tuesday on Betsy DeVos, President Trump's Education secretary nominee. Republican Sens. Lisa Murkowski (Alaska) and Susan Collins (Maine) announced last week they are breaking rank and voting against the nominee.
With no Democrats expected to support DeVos, it will be the first time ever a vice president has cast the deciding vote on a nominee. It will also be the first time a vice president has been brought in to resolve a 50-50 split since then-Vice President Dick Cheney weighed in on a tax proposal in 2008.
DeVos, a GOP megadonor, has been the subject of fierce opposition from teachers unions and other liberal groups over her support for charter schools and tuition vouchers using public funds.
