In a single tweet Friday, President Trump simultaneously hailed news of the lowest U.S. unemployment rate since 2000 and derided the ongoing special counsel probe of possible ties between his campaign and Russia in the 2016 election.

“JUST OUT: 3.9% Unemployment. 4% is Broken! In the meantime, WITCH HUNT!” Trump wrote on Twitter.

The tweet was the president’s first public comment on the unemployment rate falling to 3.9 percent — a development that Trump allies argued was evidence of his strong stewardship of the economy.

But the tweet belied the fact that the president remains irritated by special counsel Robert S. Mueller III’s ongoing investigation, which has dominated headlines, along with a payment made by Trump’s personal attorney to porn star Stormy Daniels.

Trump has repeatedly called the Russia probe a ‘WITCH HUNT,” saying that Mueller has no evidence of collusion and is trying to trap him into committing perjury.

The president and his aides have sought to highlight the progress Trump is making on multiple fronts, including in negotiations over the denuclearization of North Korea, while Democrats and the media focus on issues Trump claims are less important to real people.

Trump’s latest tweet came shortly before he was scheduled to leave the White House en route to Dallas, where he is speaking to an annual gathering of the National Rifle Association.
