With two and a half weeks left until the elections, Hillary Clinton used a pair of rallies in Pittsburgh and Philadelphia to thrust herself directly into the race for control of the Congress, as she attacked the incumbent Republican Senator running for re-election in Pennsylvania, trying to lend her help to Democratic Party efforts to take back the House and Senate.
Sen. Pat Toomey (R-PA) has stayed on the fence about Trump, as Clinton joined other Democrats who have been trying to use that to doom his re-election bid.
"If he doesn't have the courage to stand up to Donald Trump after all this, then can you be sure he will stand up for you when it counts, against powerful interests?" Clinton said to cheers.
It was also Clinton's most extended jab at a Republican in the House or Senate, as it seemed to signal that the Clinton Campaign is ready to do more than just win the White House - it wants to steer Congress into the hands of Democrats as well.
Clinton then turned her attention to Donald Trump, as she once again worked herself into a giggling fit after talking about this year's debates.
"That was the third and last time I will ever have to debate Donald Trump," Clinton said with a big laugh, as the crowd cheered.
"I have now spent four and a half hours on stage with Donald, proving again that I have the stamina to be President and Commander-in-Chief," as Clinton again was consumed by laughter.
Clinton also drew cheers when she mentioned Trump's remarks on whether he would accept the election results in November.
Clinton also talked about her reaction to Trump's line where he says that as President, he would move to make sure Clinton was put in jail for how she handled her emails while Secretary of State under President Obama.
"Every time Donald Trump says he wants to jail his opponent - meaning me - I think to myself, we don't do that in America, we actually have laws and courts, and an independent judiciary," Clinton said to applause.
Earlier in the day, Trump was also in Pennsylvania, as he used a stop in Gettysburg to set out his new, "Contract For the American Voter."
It was Trump's third stop in Pennsylvania in two days, a state where he has a lot of strong support, but the polls show him struggling to overtake Clinton.
Republicans have not won Pennsylvania in the race for President since 1988, when George H.W. Bush defeated Michael Dukakis.
