First lady Melania Trump has backed out of joining President Trump and other White House officials on a trip to a World Economic Forum in Switzerland this week, according to a report.

The first lady’s decision to cancel was because of “scheduling and logistical issues,” her spokeswoman Stephanie Grisham told CNN late Monday, the couple’s 13th wedding anniversary.

Grisham had said last week that Melania Trump would accompany her husband in a show of support to the annual gathering of some of the world’s richest and most influential people, including business titans and heads of state.

The president’s trip to Davos was in jeopardy Monday because of the continuing negotiations to end the government shutdown.

Melania hasn’t commented on allegations made by porn star Stormy Daniels that she had a sexual affair with Donald Trump four months after Melania gave birth to their son, Barron.

Daniels’ claims surfaced after In Touch magazine earlier this month published a 2011 interview with the star of “Good Will Humping.”
