The White House won't rule out moving unilaterally to address companies shifting operations overseas to avoid U.S. taxes, a spokesman said Tuesday.
"I’m not in a position to rule either in or out at this point," Earnest said.
Earlier Tuesday, three top Senate Democrats asked President Obama to examine how to prevent inversions, in which U.S. companies purchase smaller foreign companies and then combine operations outside the country to avoid paying U.S. taxes.

“We urge you to use your authority to stand up for American companies which are proud to be part of our nation and reduce U.S. incentives for others corporations which would abandon their responsibilities to their country for a nod of approval from Wall Street,” the senators added.
The White House said it would be best for Congress to pass legislation closing the tax loophole.
"It is our view that Congress should take the necessary step to address this loophole," Earnest said.
The White House spokesman also noted that Congress was able to close a loophole related to corporate inversions in 2004 with bipartisan support, despite election-year politics and a Republican president.
Earnest said he hoped the legislation would pass "quickly" and that it should be retroactive, affecting U.S. companies that have already shifted — on paper — their operations overseas.
"We should not allow companies to sort of cynically capitalize on the fact that Congress is rather slow moving these days," Earnest said.
The White House spokesman said that the administration "had not laid out a specific deadline" for Congress to act before executive action is considered.

“If we did, we would be doing more," Lew said.
On Tuesday, a spokesman for the Treasury Department said that "the best way to address inversions would be through comprehensive business tax reform," but there may be administrative actions still available.
"Treasury is reviewing a broad range of authorities for possible administrative actions that could limit the ability of companies to engage in inversions, as well as approaches that could meaningfully reduce the tax benefits after inversions take place, to at least provide a partial fix," the spokesman said.
