Hillary Clinton's campaign team accused GOP nominee Donald Trump Wednesday of being bad for American workers.

"Donald Trump's message to workers: You're fired," the Democratic presidential candidate's Twitter account read.

The tweet included an attack ad featuring a number of Trump's job creation-related promises, including when he said he would be the "greatest jobs president that God ever created."

The ad hit Trump specifically for hiring foreign workers, and for having many Trump-related products produced overseas.

Clinton's campaign team kept up the attack Wednesday, and released a graphic showing which foreign countries produce Trump products. The former secretary of state's campaign team also offered a list of approximately 100 American alternatives that the billionaire businessman can use.

"Trump couldn't be bothered to find manufacturers in America, so we did it for him," the group said in a blog post titled "Made in America: A buyer's guide For Donald Trump."

Though it is true many Trump products, including his line of vodka and neckties, are produced overseas, his business interests are also responsible for some goods made in the United States.

The GOP candidate's "Make America Great Again" hats, for example, are stitched together by a small company in Los Angeles using imported goods, according to the Associated Press.

Going after Trump on jobs and business growth is not a new tactic for the Clinton campaign, as a significant portion of the Democratic National Convention in Philadelphia last week was dedicated to this exact line of attack.

"Working people are strong, and Donald Trump is wrong, wrong, wrong," AFL-CIO President Richard Trumka told convention attendees.

"[Trump] thinks he's a tough guy. Well Donald, I worked in the mines with tough guys. I know tough guys, they're friends of mine. And Donald, You're no tough guy, you're a phony!" he added.

Billionaire businessman and former New York City mayor Michael Bloomberg suggested separately at the Democratic convention that Trump was a scam artist, and he accused the GOP nominee of having a less-than-impressive business record.

"I'm a New Yorker, and New Yorkers know a con when we see one!" he said to thunderous applause. "Truth be told, the richest thing about Donald Trump is his hypocrisy."

"Trump says he'll punish manufacturers that move to Mexico or China, but the clothes he sells are made overseas in low-wage factories. He says he wants to put Americans back to work, but he games the U.S. visa system so he can hire temporary foreign workers at low wages. He says he wants to deport 11 million undocumented people, but he seems to have no problem in hiring them. What'd I miss here?" the former mayor added.

He concluded, "[L]et's elect a sane, competent person."

Clinton and her running mate, Virginia Sen. Tim Kaine, toured separate manufacturing facilities Wednesday in North Carolina and Colorado.
