A former finance co-chair of Chris Christie's presidential campaign on Sunday slammed Christie's recent endorsement of Donald Trump, according to NBC, calling for the New Jersey governor's supporters to reject the Republican front-runner. 'Chris Christie's endorsement of Donald Trump is an astonishing display of political opportunism. Donald Trump is unfit to be President,' Meg Whitman, chief executive officer of Hewlett-Packard, said in a statement.
