WASHINGTON, March 15 (Xinhua) -- Vanessa Trump, daughter-in-law of U.S. President Donald Trump, on Thursday reportedly filed for divorce from hunsband Donald Trump Jr.

Vanessa Trump reportedly filed divorce papers in Manhattan Supreme Court, in a bid to end her 13-year-long marriage with President Trump's eldest son.

Both Vanessa and Trump Jr. are 40 years old, and have five children.

Media reports say the couple's marriage has become difficult in recent months, and Vanessa's final decision to end their bond came as Trump Jr. is under increasing pressure from Special Counsel Robert Mueller's office, as it investigates possible collusion between the Trump campaign and Russia, as well as alleged wrongdoing of the Trump Organization, which Trump Jr. manages.
