Democratic presidential candidate Hillary Clinton (L) and US first lady Michelle Obama (R) greet supporters during a campaign event at the Lawrence Joel Veterans Memorial Coliseum October 27, 2016 in Winston-Salem, North Carolina. She referred to Clinton as "my girl" and offered reassurance that her testimony for Clinton is both personal and political. "And I want to thank our first lady for her eloquent, powerful defence of that basic value".
The first lady, who has tried to stay out of the political fray during her husband's presidency, enjoys one of the highest approval ratings among Democratic figures in the country. In New Hampshire last month, she offered a stinging critique of the Republican presidential nominee after a 2005 video surfaced in which he made lewd comments about women.
Other hacked emails released by WikiLeaks show Chelsea Clinton deeply concerned that Band and other Bill Clinton aides were "hustling" for business that year for their new consultancy firm, Teneo, at the Clinton Global Initiative, the foundation's glitzy event that brings together companies, government officials and non-profit groups.
In aggregated polling across all likely voters revealed in the past week, she only had a lead of 3 per cent over Mr Trump in North Carolina, well within the margin of error.
Obama will hold an evening rally for Clinton in Orlando, along the "I-4 corridor" that's home to large numbers of potentially persuadable voters. "And she's handled them with grace", she said.
Their trip to North Carolina on Thursday coincided with the expansion of early voting statewide.
The RealClearPolitics poll average still puts Clinton ahead in Florida by 1.6 percentage points. Mitt Romney won the state by two points four years ago, despite the Democrats holding their convention in Charlotte that summer.
North Carolina is one of several battleground states - states a candidate must win if he or she wants to get to the White House. "It will be because we did not vote for her".
"Two votes - that's how presidential elections go, they are decided on a razor's edge".
Her most forceful pitch was against Trump's insistence that the election may be rigged. You can do this. "Sometimes when you get a lead, whether it's in sports or politics, you start feeling good".
"Here's two people, Hillary and Bill Clinton, who really devoted a lot to African Americans", Trump said.
With her voice quivering, Obama recalled a recent meeting with young women at the White House. Trump has fallen behind Clinton in opinion polls ahead of the November 8 election amid a series of accusations from women that Trump groped them or kissed them without their consent.
"I told them they deserve to be treated with dignity and respect", Obama said at the time.
Mrs Obama also called Mrs Clinton "my friend" and described their shared experience of raising children in the White House.
"(She) wants to lower taxes on businesses that share their profits with their employees, that properly train their employees so they can get better jobs and better incomes and that invest in areas that have been left out and left behind".
"I can't believe I'm saying a candidate for president of the United States has bragged about sexually assaulting women", Obama said at the time.
