Trump’s decision may allow him to focus on other priorities, including his policy objectives, but it’s likely to disappoint some supporters who may have voted for him based on his pledge to prosecute Clinton.

“If Mr. Trump’s appointees continue the Obama administration’s politicized spiking of a criminal investigation of Hillary Clinton, it would be a betrayal of his promise to the American people to ‘drain the swamp’ of out-of-control corruption in Washington, D.C.,” said Tom Fitton, president of the conservative group Judicial Watch, which continues to investigate Clinton. “President-elect Trump should focus on healing the broken justice system, affirm the rule of law and appoint a special prosecutor to investigate the Clinton scandals.”

The FBI has continued to investigate the Clinton family foundation, examining whether foreign governments and organizations donated money in return for State Department special treatment when she served as the nation’s top diplomat. The Clintons denied those allegations.
