Former U.S. President Barack Obama harshly criticized Donald Trump during two campaign rallies on Saturday in Ohio and Michigan, where he supported Democratic Party candidates ahead of the midterm elections scheduled for November 3.
Democrats are seeking to regain control of one or both houses of Congress, currently dominated by the Republican Party.
In both states, the 65-year-old Democrat blamed the Trump administration for rising living costs, a key concern for voters amid soaring fuel prices.
Speaking in Ohio, Obama said: "After two years of chaos, corruption, and incompetence, unlike anything we've seen in the modern era, you have the chance to say 'enough is enough,'" adding, "We're voting for change here in Ohio."
He continued: "The current president chose to make a series of bad decisions. Most importantly, he decided to wage an unnecessary war that nobody asked for."
Later, in Michigan, Obama campaigned in support of Abdul El-Sayed, who belongs to the left wing of the Democratic Party and is in a tight race against Republican Mike Rogers for a Senate seat.
"Imagine the strong duo of Abdul and Elissa," he said, referring to current Democratic Senator Elissa Slotkin.
He explained: "You have a Muslim man and a Jewish woman advocating for you in the U.S. Senate. This is something you in Michigan can be proud of."
Obama urged voters to cast their ballots as early as possible, particularly as early voting has begun in these states.
Polls in Ohio show a slight lead for Democrats, but the results are expected to be close.
Nationally, polls also indicate that Democrats could regain control of the House of Representatives, while facing significantly tougher competition in the Senate race.
Obama also criticized renovation projects carried out by Trump in various parts of the U.S. capital, including the renovation of the Reflecting Pool on the National Mall, the construction of a large banquet hall at the White House, and the addition of gold embellishments to the Oval Office during his second presidential term.
Sarcastically, he said: "He made the White House look as if Saddam Hussein opened a branch of the Cheesecake Factory in it," referring to the popular American restaurant chain known for its extravagant decor.
