Trump continues to cry as he continues to attack Biden

The retweets have highlighted the support of so-called firefighters who claim to support Trump, not Biden, despite the support of the International Association of Fire Fighters, who supported Biden on Monday.

"I have done more for firefighters than this union will ever do and I get paid ZERO!" Trump claimed early Wednesday morning.

One of the accounts, which the author claimed was that her husband was a long-time firefighter in New York and would vote for Trump in 2020, changed his name and now calls himself "F *** Donald Trump "after the president has retweeted it. The author – who replaced the avatar of a woman with the logo "Bernie 2020" in the account, then wrote: "What a beautiful morning. Seriously, our president is a horrible and hateful human being who wants nothing more than to maintain the status quo and the hatred that prevails in our country. "

A CNN poll conducted by the SSRS after Biden's announcement last week has confirmed its status as a Democratic leader, with 39% of Democratic voters or independent Democrats saying it's their first choice for the nomination .

Trump seemed taken aback by Biden's candidacy and support from the unions, and launched attacks on the former vice president despite the advice of his political advisers not to get caught off guard by any of the leading candidates for the Democratic nomination.

Several of the president's political advisers cautioned against targeting Biden and reacting to attacks by Democratic candidates, fearing that Trump would raise a potential rival, sources told CNN.

During his meetings at the White House, Trump often asked about Biden's strength as a candidate as Biden prepared more and more to officially enter the race.

In his announcement of the presidential campaign and his trip Tuesday in Iowa, Biden congratulated Trump on his response to the White Supremacy Rally in 2017 in Charlottesville, Virginia.
