Hillary Clinton began a Labor Day rally in Cleveland with a bad cough — which she blamed on her opponent, Donald Trump.

“Every time I think about Trump, I get allergic,” Clinton said after some sustained hacking.

“Boy, we have 63 days to go,” Clinton croaked, before coughing some more.

Tim Kaine, Clinton’s running mate, sat awkwardly behind her, trying at times to rally her supporters.

“USA! USA! USA!,” the crowd chanted.

Clinton sipped on water.

“Well, you just heard the next vice president,” Clinton continued, her voice never fully recovering.
