Democrats slam Trump's tweet about Sen. Gillibrand

President Donald Trump started a Twitter feud with Sen. Kirsten Gillibrand of New York. Top Democrats are coming to her defense after she suggested the president resign amid allegations of past sexual misconduct.

Trump refused  to answer questions about his tweet attacking Gillibrand. In it he called Gillibrand a "lightweight" who came to him "begging" for campaign contributions and "would do anything for them."

Gillibrand called the tweet a "sexist smear attempting to silence" her. She said she won't be silenced. Gillibrand said Trump should resign because more than a dozen women have him of past sexual misconduct.

Trump has repeatedly denied the women's accusations.

White House Press Secretary Sarah Huckabee Sanders said the president's tweet about Gillibrand referred to political corruption and was not sexual innuendo.

Top Democrats were furious. Sen. Elizabeth Warren of Massachusetts tweeted: "are you really trying to bully, intimidate and slut-shame @sengillibrand?"

Senate Minority Leader Chuck Schumer echoed that sentiment. He said the tweet was "nasty" and "unbecoming of the president." Schumer said Trump "ought to stop tweeting and start leading."

The Democratic women's working group sent a letter to the U.S. House oversight committee asking for an investigation.

To date, more than 17 women have come forward to accuse Trump of sexual misconduct, forced kissing, unwanted touching, and groping.

The wife of a former New York Ranger said that she, too, had an experience with Trump in the 1990s while the two were in an elevator at Madison Square Garden. Stacia Robitallie, the wife of former NHL star Luc Robitalle, tweeted that Trump was aggressive. "He told me I was coming home with him. I laughed, stating I was married to a Ranger," she tweeted. "He guaranteed me my husband didn't make as much money as him."
