Protesting Hispanic-American groups have urged NBC to revoke an invitation to Donald Trump to guest host Saturday Night Live.  

They gathered outside the network's offices in New York urging bosses to think again.

Trump outraged many in June when he described Mexican migrants as rapists and drug smugglers. 

Trump has also repeated his intention to get Mexico to pay for a wall to secure the U.S. southern border. 

NBC said Saturday Night Live would not comment on the Trump controversy.
