Former first lady Michelle Obama denounced trump as “the wrong president” at the National Congress on the 17th local time. In response, trump tweeted on the 18th, criticizing Obama and Biden’s dereliction of duty, and said sarcastically to Michelle: “thank you for your kind words.” According to the “Capitol Hill” reported on the 18th, U.S. President trump tweeted early that morning: “please explain to Michelle Obama that if your husband Obama is not incompetent, I would not be here in this beautiful white house.” Trump continued to ridicule Obama’s insincere support for Biden. “From that late endorsement without any passion, we can see that Biden was just something he remembered later.” Then trump wrote a second tweet praising his achievements: “I’ve built the greatest economy of all time.” “Employment is increasing, and the NASDAQ index is at a new high.” He also defended the authorities’ response to the new outbreak and compared it with the Obama administration. “Historically, the response of Obama and Biden’s team to the H1N1 flu was seen as weak and pathetic. It’s really bad to look at the polls at that time.” “Obama and Biden formed the most corrupt government in history, and they were also found spying on my campaign, the biggest political scandal in our country.” Michelle Obama, the former first lady of the United States, delivered a video address on the first night of the 4-day US National Congress, accusing the White House of “confusion, division and lack of compassion”. According to the schedule, Biden will formally accept the presidential nomination by delivering a long-distance speech in Delaware, where he lives, on the closing night of the Congress on the 20th. The Republican National Congress will be held in Charlotte, North Carolina from the 24th to the 27th, with a long-distance speech on the closing night of the online day to accept the Republican presidential nomination, Reuters reported on the 17th.
