According to a report in The Atlantic published Thursday, Trump made disparaging comments about American troops, which included skipping a visit to the cemetery in France honoring fallen soldiers in the Battle of Belleau Woods, who he reportedly dismissed as "losers".
Biden's campaign has made a concerted effort to fire back at Trump and cut into his military voting bloc. The Atlantic also reported that Trump asked for wounded veterans to be kept out of military parades. The White House has denied the claims, and said the trip was canceled due to weather conditions.
Mr Trump has furiously defended himself in the wake of the story in The Atlantic, tweeting and retweeting stories condemning it as "fake news". Going further, he said Trump has the "deepest respect" for the US armed forces.
Three sources also claimed that Trump also called late President George H W Bush a "loser" for being shot down and taken prisoner as a US Army Air Force pilot during the Second World War.
Trump's next target was journalist Jennifer Griffin, the national security correspondent for Fox News - once considered one of the most pro-Trump stations. "I've never seen that".
The president, seeking re-election on a promise to restore "law and order", told Fox News the plane was "completely loaded with thugs wearing these dark uniforms, black uniforms with gear and this and that", adding, "Here were like seven people on the plane like this person and then a lot of people were on the plane to do big damage".
Democratic and Republican opponents alike over the weekend seized on the reports - which said that Trump had called USA soldiers buried in Europe "losers" - to attack his record on the military on news shows and in political ads.
"Anyone who knows President Trump has seen his love and reverence for our military and veterans".
"It has become a very unsafe time when anonymous sources are believed above all else, & no one knows their motivation", she tweeted, calling The Atlantic's reporting "not journalism" but rather "activism" and hence "a disservice to the people of our great nation".
Former US Army officer and political analyst Scott Bennett told Sputnik the Democrats have a four-stage strategy to "steal the presidential election".
"I welcome him to do either of those things", Tarlov said.
