WASHINGTON (Reuters) - Aides to U.S. President Donald Trump on Sunday attacked the credibility of the nonpartisan agency that will analyze the costs of a replacement for Obamacare, as the White House sought to quell opposition from many Republicans.

The Congressional Budget Office, which provides official estimates of the budget impact of proposed legislation, is expected to issue a report as early as Monday that will assess the healthcare legislation put forth by Republican House of Representatives leaders.

The Trump administration's criticisms of the CBO are unusual. Prior administrations, both Republican and Democratic, have steered clear of attacking the credibility of the agency, which many lawmakers regard as a neutral arbiter. The CBO's current director, Kevin Hall, was appointed by Republicans in 2015.
