WASHINGTON — The White House wants the National Security Agency to get out of the business of sweeping up and storing vast amounts of data on Americans’ phone calls.

The Obama administration this week is expected to propose that Congress overhaul the electronic surveillance program by having phone companies hold onto the call records as they do now, according to a government official briefed on the proposal. The New York Times first reported the details of the proposal Monday night.

The White House proposal would end the government’s practice of sweeping up the phone records of millions of Americans and holding onto those records for five years so the numbers can be searched for national security purposes. Instead, the White House is expected to propose the phone records be kept for 18 months, as the phone companies are already required to do by federal regulation, and that it be able to preserve its ability to see certain records in specific circumstances approved by a judge.

According to a senior administration official, the president will present “a sound approach to ensuring the government no longer collects or holds this data, but still ensures that the government has access to the information it needs to meet the national security needs his team has identified.” The administration official spoke late Monday on condition of anonymity because he was not authorized to publicly discuss the proposal before it was officially announced.

The president’s plan, however, relies on Congress to pass legislation — something that has so far seemed unlikely.

Details of the government’s secret phone records collection program were disclosed last year by former NSA systems analyst Edward Snowden. Privacy advocates were outraged to learn the government was holding onto phone records of innocent Americans for up to five years. Obama promised to make changes to the program in an effort to win back public support.

In January, President Barack Obama tasked his administration with coming up with an alternative to the current counterterrorism program and suggested the phone companies option was the most likely. However, he also said that option posed problems.

“This will not be simple,” Obama said. An independent review panel suggested that the practice of the government collecting the phone records be replaced by a third party or the phone companies holding the records, and the government would access them as needed.
