Democratic presidential nominee Hillary Clinton campaigned with her running mate, Senator Tim Kaine, in Pittsburgh on Saturday (October 22), the first time the two have campaigned together in weeks.

Kaine urged supporters to "do their best" to elect Clinton the nation's first female president, while Clinton focused on the short-comings of her rival, Republican presidential nominee Donald Trump.

Clinton took aim at Trump's threat to put her in jail if he's elected saying, "We don't do that in America. We actually have laws, and courts and an independent judiciary." She also criticized Trump's call to make it easier to sue media outlets, telling the crowd, "We believe in a free press."

Her comments come just hours after Trump vowed to foil a proposed deal for AT&T to buy Time Warner if he wins the Nov. 8 election, arguing it was an example of a "power structure" rigged against both him and voters. Telecommunications company AT&T Inc has agreed in principle to buy Time Warner Inc, one of the country's largest film and television companies, for about $85 billion and an announcement could be made as early as Saturday. Trump also said he would look at "breaking" up the acquisition by Comcast Corp of the media company NBC Universal in 2013.

Trump is trailing Clinton in most polls. Clinton also has a commanding lead in the race to win the Electoral College, a Reuters/Ipsos States of the Nation project poll released on Saturday showed.
