Donald Trump took a new swipe at Bill and Hillary Clinton on Tuesday, tweeting a double-barreled insult about the former president's economic record and his penchant for messing around.

Hillary said Sunday that she plans to put her husband in charge of revitalizing the American economy if she wins the White House.

Trump said the former secretary of state should be able to do the job herself – and hinted that the famously randy Bill could bring a host of troubles with him if he returns to 1600 Pennsylvania Avenue.

'Crooked Hillary said her husband is going to be in charge of the economy.If so, he should run,not her,' Trump tweeted. 'Will he bring the "energizer" to D.C.?'

That's a reference to Julie McMahon, a Clinton neighbor in Chappaqua, New York, who reportedly carried on a years-long love affair with the former president, visiting when his wife wasn't around.

NOT MESSING AROUND: Trump's social media attacks on 'Crooked Hillary,' his pet name for Mrs. Clinton, have become more and more pointed and aggressive

Her drop-ins became such a hot topic of conversation among Bill's Secret Service detail, according to Ronald Kessler's 2014 book 'The First Family Detail: Secret Service Agents Reveal the Hidden Lives of Presidents,' that she got her own call-sign nickname.

'The Energizer' was a play on the bunny in the Energizer battery commercials – an electronic toy that 'keeps going and going and going.'

Agents told Kessler that they were under orders not to stop, approach or question his blonde paramour.

McMahon was in the news last week after a Wall Street Journal report identified a company partially owned by McMahon as the beneficiary of $2 million from the Clinton Global Initiative.

'It's a bombshell – there's no doubt about it,' Trump said Friday.

'It's a rough story and a lot of people know about it, and people have been talking about it for a couple of years,' he told a Fox News Channel audience.

PACKAGE DEAL, PART II? Bill Clinton touted his wife's strengths in 1992, telling Americans they were getting two for the price of one – and now Hillary wants to return the favor by mentioning Bill as n economic czar

The company, Energy Pioneer Solutions, is 2- percent owned by McMahon.

The alleged financial and romantic hanky-panky is what got Trump in a lather on Tuesday.

Hillary said Sunday in Kentucky that 'I'm going to put [Bill] in charge of revitalizing the economy because you know, he knows how to do it. And especially in places like coal country and inner cities and other parts of our country that have been really left out.'

Trump, however, has railed against Bill Clinton's less-productive economic moments – including the North American Free Trade Agrement, which he says cost the U.S. millions of jobs as companies chased cheap labor into Mexico.

'How can Crooked Hillary put her husband in charge of the economy when he was responsible for NAFTA, the worst economic deal in U.S. history?' Trump wrote Tuesday on Twitter.

Mrs. Clinton has not spelled out exactly what her husband would do as her economic czar, where he would work, or what limits if any would be placed on his issue portfolio.

The President of the United States typically relies on a range of advisers for guidance on the economy. Most are on the public payroll and some, such as the Secretaries of Treasury and Commerce, are subject to confirmation by the U.S. Senate.

KEEPS GOING AND GOING AND GOING: McMahon reportedly had drop-in privileges at the Clinton home in upstate New York, with Secret Service agents being told not to approach her, stop her or question her

Trump has telegraphed his willingness to go after the Clintons on personal issues, including the Monica Lewinsky scandal, as a way to hit back at Hillary Clinton for charging him with sexism.

'She's been playing the woman card and I have to hit her back whenever she does that. It's all nonsense ... Nobody has more respect for women then a do,' he said.

The financial commitment to a company stocked with close Clinton pals came at the 2010 conference of the Clinton Global Initiative, the Wall Street Journal reported, citing a document from the time and people familiar with the matter.

In another boost for the firm, Clinton personally intervened with then Energy Secretary Stephen Chu, the paper reported. The feds gave the company an $812,000 grant, the Energy Department said on its web site.
