Former Puerto Rico House Speaker Jenniffer Gonzalez said she considers the move as a type of receivership.
"It shows the lack of trust that the federal government has concerning the capacity of the current administration over economic and fiscal matters," said Gonzalez, a representative affiliated with the pro-statehood New Progressive Party.
While Gov. Alejandro Garcia Padilla did not respond to requests for comment regarding the announcement, his chief of staff Ingrid Vila rejected Gonzalez's comments.
"There is no federal takeover of Puerto Rico," she said. "Our economic plan is working, and we are continuing to work through the next phases of our plan, which includes tapping the Obama Administration for advice on how we can maximize our federal resources, so that we can grow the Commonwealth's economy."
The U.S. administration official stressed that the federal government routinely has conversations about similar initiatives with governors, mayors and county leaders across the U.S., noting there's a current initiative called "Strong Cities, Strong Communities" in which federal teams work inside city halls to encourage economic growth.
The team was created by a presidential task force that has previously worked with Puerto Rico on issues related to its political status. President Bill Clinton created the task force in 2000 to analyze Puerto Rico's status, but President Barack Obama's administration expanded its scope to make recommendations on policies affecting areas such as education, health care and economic development.
The task force includes members from every Cabinet agency and issued its last report in March 2011.
Formation of the team follows recent speculation that Washington might step in to help the Caribbean territory's government as it struggles with $69 billion in public debt and a 13.9 percent unemployment rate, higher than any U.S. state.
The island's general obligation bonds have been hovering at just above near-junk status.
In September, Puerto Rico's Government Development Bank announced it would cut bond sales after investors pushed the yield on Puerto Rico bonds above 10 percent. Shortly afterward, Garcia said he would increase the borrowing capacity of Puerto Rico's main debt issuer, the Sales Tax Financing Authority.
Garcia also has taken other measures to appease Wall Street ratings agencies, including the reformation of a public pension system that had a $37.3 billion unfunded liability.
The federal officials will work with Garcia to outline joint economic goals, with a review expected in about six months. Helping the team will be U.S.-based officials with the Office of Management and Budget, the National Economic Council and the Treasury Department.
