(CNN)First lady Melania Trump gave her fourth solo campaign speech on Monday afternoon in Huntersville, North Carolina. Trump, who before last Tuesday had not appeared on the campaign trail for more than a year, slammed Democrats in remarks that touched on Covid-19, the military, and echoes of President Donald Trump's law and order messaging.

"When rioters and looters were burning our cities and wrecking small businesses that belong to hard working families and bring jobs to our communities, where were the Democrats?"Trump said in a speech similar in content to the two she gave Saturday in Wisconsin and Pennsylvania.

The first lady's remarks on the trail have been explicitly partisan and more combative than most of the public remarks she has given during her tenure in the White House. Trump also targeted Democratic presidential nominee Joe Biden.
