Federal and State Income Taxes [Abstract] |

Schedule of Effective Income Tax Rate Reconciliation [Table Text Block] | Historically, our effective tax rate differed from the statutory rate primarily due to partnership earnings that are not subject to U.S. federal and most state income taxes at the partnership level. The completion of the Southern Union Merger, Sunoco Merger, ETP Holdco Transaction and the Susser Merger (see Note 3) significantly increased the activities conducted through corporate subsidiaries. A reconciliation of income tax expense (benefit) at the U.S. statutory rate to the income tax expense (benefit) attributable to continuing operations for the years ended December 31, 2016, 2015 and 2014 is as follows:
| December 31, 2016 |  | December 31, 2015 | December 31, 2014
Income tax expense (benefit) at U.S. statutory rate of 35 percent | $ | 95 |  |  | $ | 302 |  |  | $ | 462 |
