Former US President Barack Obama joins the Democratic Party's campaign for the midterm elections and directs harsh criticism of the Republican Party and President Donald Trump.

Former US President Barack Obama harshly criticized Donald Trump during two election rallies in Ohio and Michigan to support Democratic Party candidates ahead of the midterm elections scheduled for November 3.

Democrats are seeking to regain control of one or both chambers of Congress, which are currently controlled by the Republican Party.

The former president maintains great popularity among the Democratic base, and he is keen to use it to support his party's candidates in the decisive elections. In both states, Obama held the Trump administration responsible for the high cost of living, which is one of the main issues preoccupying voters in light of the significant rise in fuel prices.

"After two years of chaos, corruption, and incompetence, the likes of which we have never seen in modern times, you have the opportunity to say 'enough is enough,'" Obama said in Ohio on Saturday, adding, "We are voting for change here in Ohio." He continued, "The current president chose to make a series of bad decisions. More importantly, he decided to launch an unnecessary war that no one asked for."

Later, in Michigan, Obama participated in a campaign to support Abdel Sayed, who belongs to the left wing of the party and is locked in a tight race with Republican Mike Rogers to win a seat in the Senate. “Imagine the strong duo of Abdel and Elissa,” he said, referring to the current Democratic Senator Elissa Slotkin.

He explained, "You have a Muslim man and a Jewish woman defending you in the US Senate. This is something you in the state of Michigan can be proud of." He called on voters to cast their votes as soon as possible, especially since early voting has begun in these two states.

Opinion polls in Ohio show a slight lead for Democrats, but the results are expected to be close. At the national level, opinion polls also indicate that Democrats may regain control of the House of Representatives, but they face much tougher competition in the race for the Senate.

Obama also criticized the restoration and renovation projects implemented by Trump throughout the American capital, including the failed restoration of the Reflecting Pool on the National Mall, the construction of a huge ballroom in the White House, and the addition of gilded decorations to the Oval Office during his second presidential term. He said sarcastically, "He made the White House look like Saddam Hussein had opened a branch of the Cheesecake Factory there," referring to the chain of American restaurants famous for their exaggerated decor.

For his part, US President Donald Trump announced on Saturday that the German car manufacturer Audi intends to invest $4.2 billion to establish its first factory in the United States, which will produce 200,000 vehicles annually. The German company confirmed the investment in a statement, noting that the factory will provide about 4,500 job opportunities.

“I am pleased to announce a huge investment in automobile manufacturing in the great state of Georgia by a wonderful company,” Trump said at a campaign rally in Perry, Georgia, 10 days before the election. He added, "Audi has just committed to investing $4.2 billion in the state of Georgia, to begin construction next month of a huge factory that will produce 200,000 cars annually. This is incredible."

The company, a subsidiary of the Volkswagen Group, said in a statement that construction work is scheduled to begin next year, with production starting in the early 2030s. She explained, "The planned investment aims to confirm a long-term commitment to the United States, and to establish North America as a third major pillar within Audi's global production network, alongside Europe and China." The factory will produce luxury SUVs, specifically designed to meet the requirements of customers in North America.
