Those tariffs came as a result of Trump's decision to impose steep duties on steel and aluminum imports Europe and elsewhere last month. Mr. Trump knows nothing about economics and even less about trade. The company was inundated with queries about its veracity.
The president had earlier warned that any shift in production "will be the beginning of the end".
He said the company has been working with Twitter to see if the tweets could be removed and to figure out where they originated. The company had no immediate response Tuesday to the president's assertions.
Pflughoeft would not speculate as to whether there was a coordinated smear campaign at work against Harley's chief executive.
One day after the Wisconsin-based company said it was planning to shift some manufacturing overseas due to the European Union's tariffs in retaliation for USA duties, Trump accused Harley-Davidson of appropriating the trade war as an "excuse" for the move. "I've done so much for you, and then this".
The company reiterated Tuesday that it was moving some production of motorcycles destined for sale in the European Union to its existing global facilities to "address the additional tariffs imposed by the European Union".
But Harley-Davidson's plight in Europe drew fresh interest from French Parliament member Eric Straumann, who contacted Levatich to propose a new factory on the French-German border in Alsace.
This week Harley said it would move production of motorcycles bound for Europe overseas, blaming European Union tariffs that it said would add $2,200 to the cost of an average bike.
Trump has not taken the decision lightly and has lashed out in a series of tweets over the past two days.
MrTrump ridiculed the company for building motorcycles overseas.
Harley-Davidson shares closed down 0.6 percent at $41.32, after falling almost 6 percent on Monday.
Steven Mnuchin, the Treasury secretary, also expressed his dismay with Harley-Davidson on Wednesday, saying during remarks at the Treasury Department that Trump has been a big champion of trying to help Harley by reducing tariffs on motorcycles and cutting corporate taxes.
S&P's rating for Harley is A-minus - not sterling but in the top tier.
Tweets from Trump can be damaging to businesses, quickly mobilizing his supporters in protest. A representative from the White House did not respond immediately to a request for comment.
