Ivanka Trump has faced widespread criticism online after taking to Twitter on Monday to praise Oprah Winfrey for her Golden Globes speech which called out sexual abusers and promised "a new day is on the horizon".

The daughter of US President Donald Trump voiced her support for Winfrey's "empowering & inspiring speech" and called on everyone to come together and say "#TIMESUP", referencing the campaign launched this month by women in Hollywood to fight sexual harassment.

The backlash to Trump's tweet was swift, with many social media commenters pointing out that her father has faced multiple accusations of sexual misconduct, all of which he denies, and was also caught on video making lewd remarks about women in a leaked Access Hollywood video from 2005.

Actor Alyssa Milano replied to Ivanka Trump's tweet by urging her to donate to the Time's Up Legal Defense Fund to "support your father's accusers".

Model and presenter Chrissy Teigen simply wrote: "ew go away".

Journalist Jennifer Rubin slammed Ivanka's tweet as "hypocritical" and "clueless" and referenced the President's support of Republican politician Roy Moore, who was accused of sexual misconduct.

She added that "YOU are indeed part of the problem Ivanka".

Michael Wolff, the author of Fire and Fury, the explosive new book about Donald Trump and the White House, appeared on MSNBC's The Last Word where he said Ivanka's "head is in the clouds" or she is in "denial".

Other Twitter users voiced their incredulity about the tweet.
