Ivanka Trump has been vocal in using her White House role to advocate for women. But when US President Donald Trump lobbed a demeaning attack on a female TV host on Twitter this week, his daughter and

senior adviser kept quiet.

The tussle between her father and "Morning Joe" co-hosts Mika Brzezinski and Joe Scarborough offered a pointed reminder to Ivanka Trump that this is a city where it's impossible to separate policy and politics.

The MSNBC hosts, in a Washington Post column yesterday, called on women close to the president to condemn him for questioning Brzezinski's intelligence and saying that she was "bleeding badly from a face-lift" in a December encounter.
