Only one of the three links is partially correct and it sure is not Senator Edward J. Markey (D-Mass.). Did you know that many countries have sent their crude to the gulf coast refineries to be refined and returned to their countries?

From wall street journal article:

Since then, U.S. oil production has grown and demand has stagnated. As a result, U.S. refineries are increasingly cranking out gasoline, diesel and jet fuel for overseas markets, in particular Latin America.U.S. exports of refined products have nearly tripled since 2005, according to government data, and the U.S. became a net exporter of those products in 2011.

Tapping Canadian oil would help displace imports of crude oil from countries such as Venezuela and Mexico, said Marty Durbin, executive vice president at the American Petroleum Institute, a trade group.

This is one of the few sectors that has prevented a complete collapse of the balance of trade. Oil in fungible. Do you know what that means?

Nothing in the links go counter to what I said. The oil will be refined and exported to other markets. Trans has already said of potential rises in oil prices and such.

Crude is refined all the time on the gulf, it is not often that citizens lose their property to private interest that benefit other than US citizens. Land and property is taken and that will benefit the Chinese and other countries.
