(HUFFINGTON POST) NBC chief Bob Greenblatt said that the network is keeping watch over “Apprentice” host Donald Trump.

The real estate mogul stoked controversy with his repeated harassment of President Obama during the 2012 election. Barbara Walters implored Trump to stop, and even his own children reportedly intervened.

Deadline Hollywood reported that Greenblatt addressed the network’s controversial star at the 2013 winter Television Critics Association press tour on Sunday.
