Some Democratic lawmakers and interest groups allied to the president support the measures, but international allies and trading partners are warning that favoring U.S. companies would breach U.S. trade commitments and could set off tit-for-tat countermeasures around the world.
The two largest U.S. trading partners already have spoken out against the measures. On Thursday, Canadian Prime Minister Stephen Harper expressed concern and the European Union warned that it would not "stand idly by" if such measures were passed. On Friday, Brazil's president Luiz Inacio Lula da Silva also criticized the measures.
In November, world leaders, who gathered in Washington for the G-20 summit to consider how to right the global economy, pledged to avoid protectionism. But since taking office Jan. 20, Obama has said little on trade and has yet to nominate a trade representative. While campaigning, he argued that the Bush administration's strong support of free trade agreements should be moderated by including environmental and labor protections.
"The jury is out on how this administration is going on trade policy," said Steven Schrage, an international business analyst at the Center for Strategic and International Studies. "This will be a key test."
Asked about the protective provisions Friday, White House press secretary Robert Gibbs would say only that the administration was reviewing them.
The provisions are likely to find support among Americans outraged that money from a stimulus package likely to top $800 billion could go to foreign competitors of U.S. firms.
"I believe that when taxpayer dollars are used, they should support the things produced here at home," Democratic Sen. Byron Dorgan, author of one of the provisions, said in a statement.
Many analysts say the measures reflect the interests of small sectors over the larger economy, which could suffer from reduced trade and higher steel prices.
"The result, according to my calculations, is that the U.S. will lose more jobs than it will gain," said Gary Hufbauer, an economist with the Peterson Institute for International Economics, a Washington think tank. "We are going to poison the wells of world commerce if we do this."
