The Westboro Baptist Church has announced that it plans to picket the funeral of Vice President Joe Biden's son Beau Biden on Saturday (6 June). Forty-six-year-old Biden died on 30 May 2015 from brain cancer.

In a post on its website on Wednesday, the Westboro Baptist Church said it would protest for at least one hour at the Wilmington, Delaware funeral. The controversial group criticised the vice president, saying, "Joe Biden has enraged the LORD his God, such that His judgements are upon Biden and his family in wrath."

According to the NY Post, the group known for picketing soldiers's funerals said: "As for Beau Biden, his life was cut short by the will of God to whom all glory is given and he has an eternity of answering to the Lord for his own words, thoughts, actions and sins."

"[Joe] Biden has a lifetime of rebellion to seek repentance for before his soul is required of him," the group said of the vice president. "The time is short. Repent or likewise perish."

The Westboro Baptist Church went one step further and said: "Beau would want you to listen to WBC and repent TODAY!"

CNN reported that thousands of mourners paid their respects to Biden on Friday at St Anthony of Padua Roman Catholic Church. President Barack Obama and First Lady Michelle Obama are expected to travel to Wilmington for the funeral mass, where the president will give the eulogy.

Biden, who served as Delaware Attorney General and was a war veteran, is survived by his wife Hallie and his two children, Natalie and Hunter.
