Republican nominee Donald Trump will hold his first public campaign rally since a shocking assassination attempt a week ago by appearing in a crucial rust belt battleground state alongside his new running mate, Ohio senator JD Vance, Ednews reports citing The Guardian.

The return to the campaign trail by Trump comes after the attempted killing of the former US president at a Pennsylvania rally last Saturday when a 20-year-old gunman opened fire, injuring Trump and others and killing one rally-goer.

The shooting roiled American politics, ratcheting up the tension in a race already fueled by fears over rising political violence and the prospect of civil unrest. It also dominated the past week’s Republican national convention in Milwaukee from which Trump emerged at the head of a remarkably unified and energized campaign.

Tonight’s joint rally with Vance is the first for the pair since they officially became the nominees. Trump kicked off the gathering of Republicans by naming Vance his vice-presidential pick.

Michigan is one of the crucial swing states expected to determine the outcome of the presidential election. Trump narrowly won the state by just more than 10,000 votes in 2016, but Democrat Joe Biden flipped it back in 2020, winning by a margin of 154,000 votes on his way to the presidency.

With Vance by his side, Trump will deliver remarks in Grand Rapids, a historically Republican stronghold that has trended increasingly blue in recent elections.

Trump’s choice of Vance was seen as a move to gain support among so-called rust belt voters in places such as Michigan, Pennsylvania, Wisconsin and Ohio who helped Trump notch his surprise 2016 victory.

Vance specifically mentioned those places during his acceptance speech at the Republican national convention, stressing his roots growing up poor in small-town Ohio and pledging not to forget working-class people whose “jobs were sent overseas and children were sent to war”.

Democrats have dominated recent elections in Michigan, but Republicans now see an opening in the state as Democrats are increasingly divided about whether Biden should drop out of the race.

Biden has insisted he is not dropping out, and has attempted to turn the focus back towards Trump, saying on Friday that Trump’s acceptance speech at the Republican national convention showcased a “dark vision for the future”.

In polls over the last week, Trump has often extended his narrow lead over Biden, though the race overall remains close. Trump, however, is continuing to perform strongly in the crucial battleground states that are vital for victory. His campaign also insists that the contest is broadening to bring in some states – such as Virginia – that Democrats previously considered safe.
