That is not the complete quote.
The other always excluded important part of this quote is the terms negotiated in the lawsuit by Clinton’s lawyers.
“Sexual relations” was defined as having contact with another’s genitals. Since he never contacted hers, the statement is literally correct as far as the lawsuit is considered. But in everyday parlance, not so much.
Unfortunately for Ms Lewinsky, the definition precludes her from saying she did not have sexual relations with that man.
Clinton was very disingenuous and misleading.
His law license was suspended for 5 years for perjury by the Arkansas bar after he left the White House.
