Pipeline companies in the U.S. will benefit under a Trump administration, because regulations will likely be relaxed, according to Brian Zarahn, a senior analyst at Mizuho Securities. Zarahn expects the next administration will approve the proposed Dakota Access Pipeline, which has several owners including Energy Transfer Partners (ETP) , Energy Transfer Equity  (ETE) , and Sunoco Logistics Partners (SXL) . Zarahn says those companies are well positioned to benefit once that pipeline goes into service. The pipeline is also backed by mater limited partnerships Phillips 66 Partners (PSXP - Get Report)  Enbridge Energy Partners (EEP)  and MPLX (MPLX - Get Report) . TheStreet's Rhonda Schaffler spoke with Zarahn on the Mizuho trading floor in New York.
