30 minutes later, she said she felt Alexander's hand grab the back of her arm and grope around her ribs, then her breast.
A Florida man accused of groping a female passenger on a Southwest Airlines flight Sunday allegedly told authorities that the president of the USA "says it's OK" to grab women by their private parts, according to a criminal complaint.
The video was released in October 2016, after Trump became the Republican nominee for president.
The woman told investigators she had fallen asleep shortly after takeoff and the first time she felt a touch on her sweater she thought it was an accident.
The woman then stood up and told Alexander she did not understand how he could think that was OK and he needed to stop.
Alexander is alleged to have grabbed a woman's breast twice while he sat behind her on the flight to New Mexico.
Alexander made the comment about the president to an Federal Bureau of Investigation agent, in an apparent reference to a 2005 conversation caught on video by Access Hollywood in which Donald Trump bragged in vulgar terms about kissing, groping and trying to have sex with women.
The woman said she saw a hand with thick, hairy fingers and dirty fingernails, according to the complaint.
A crew member relocated the woman to a different seat.
Just last week, a Texas man flying from Los Angeles to Dallas allegedly did not stop touching the woman seated next to him and attempted to engage her in an unwanted game of "footsies", according to a criminal complaint.
In a written statement to federal agents, Alexander said he was asleep for most of the flight and had not been drinking alcohol or taking any sleep aids.
A spokeswoman for the US attorney for the state of New Mexico said Alexander is being held in federal custody pending a preliminary hearing and a detention hearing set for today. He was seeking a court-appointed lawyer and was being held at the Sandoval County Jail.
If convicted, Alexander could face up to two years in prison and a $250,000 fine, according to the U.S. Attorney's Office.
