In Cleveland, Ohio, Mrs Clinton ended the day’s campaigning at a concert, where she was joined by the singer Beyonce and her husband, rapper Jay Z.
“We have unfinished work to do, more barriers to break, and with your help, a glass ceiling to crack once and for all,” Mrs Clinton said.
Addressing the crowd, Jay Z explained his support for Mrs Clinton. He said that though he did not have any “ill will” towards Mr Trump, the Republican’s conversation was “divisive”.
“That’s not an evolved soul to me, so he cannot be my president. He cannot be our president,” he said.
The free concert was part of a series of events put on by Mrs Clinton’s campaign as she aims to encourage greater African-American participation in the election.
Mr Trump, meanwhile, told a crowd of supporters in New Hampshire that his rival wants a “550% increase” on Syrian refugees allowed into the US.
“Her plan would mean generations of terrorism, extremism, and radicalism spreading into our schools and communities,” the Republican candidate said.
