Both presidential candidates are working, even on Labor Day.

FOX's Rachel Sutherland reports: 

Both Republican Donald Trump and Democrat Hillary Clinton are campaigning in Ohio where polls have been tightening over the past couple of weeks.

On ABC's "This Week", Trump campaign manager Kellyanne Conway criticized Clinton for rarely holding news conferences: 

(Conway) "She's being told, just prepare for a landslide, run out the clock. Don't go talk to the voters."

Clinton's running mate Tim Kaine defended her, saying she talks to journalists on the campaign trail regularly. The first Presidential debate is three weeks from tonight.
