White House spokesman Jay Carney said Tuesday that the State Department was reviewing the project and he did not want to "get ahead of that process."
Once that review is completed, "we'll obviously address that issue," Carney said.
Meanwhile, Secretary of State nominee John Kerry said he plans to divest holdings in dozens of companies in his family's vast financial portfolio to avoid conflicts of interest if he is confirmed by the Senate.
Kerry, a Massachusetts Democrat, said he would not take part in any decisions that could affect the companies he has holdings in until those investments are sold off. Among the investments are holdings in two Canadian companies, Suncor and Cenovus Energy Inc., both of which have publicly supported the Keystone XL pipeline. Kerry's investments are in family trusts.
