"Many people are saying" things about Donald Trump, but not in the way the Republican nominee may want.

Twitter hashtag "many people are saying" began trending nationally late Monday after Trump tweeted a comment pushing the idea the public believes former Secretary of State Hillary Clinton was connected to the execution of an Iranian scientist.

Those opposed to and in support of Trump turned out on Twitter to chime in their two cents, as well as random Twitter users looking to push their non-political hobbyhorses.
