Donald Trump's White House adviser's Twitter account retweeted a white nationalist on Tuesday, and then sent a Valentines day "love" tweet back to the user.

Kellyanne Conway deleted the exchange, on her account when Buzzfeed highlighted the exchange, and said she had not sent the messages saying she "denounced" whoever it was.

Mrs Conway has been under pressure to explain why she went on television this week to insist that Michael Flynn, Mr Trump's national security adviser, had the "full confidence" of the president, hours before he was forced from the White House.

Amid this criticism, a Twitter user, Lib Hypocrisy, sent her a message complimenting her for her “strength and resiliency in face of vile hatred, bigotry, & sexism of the unhinged Left".

Mrs Conway's twitter account re-tweeted the message. And then sent a response saying: "Love you back!" and wished her “Hapless Haters” a happy Valentine’s Day.
