Joe Biden may need to brush up on his history.
Biden, the presumptive 2020 Democratic presidential nominee, reminded Democratic Pennsylvania Gov. Tom Wolf Wednesday that he was once known as Pennsylvania's third senator when he was neighboring Delaware's 36-year representative in the U.S. Senate.
In response, Wolf jokingly teased during the virtual event that Delaware once fell under Pennsylvania's authority.
"But we declared our independence on Dec. 7 by the way, it's not just D-Day," Biden, the two-term vice president, replied.
All of this is wrong:

▶️Delaware declared its independence on June 15, not December 7 (the date it ratified the Constitution)
▶️ D-Day was June 6, not December 7 (that's the date of the attack on Pearl Harbor) pic.twitter.com/OI5oneBOo4
The state of Delaware, however, was established on June 15, 1776, when it declared its independence from Britain and Pennsylvania. The Allied World War II D-Day invasion of Nazi Germany controlled-Normandy, France, was on June 6, 1944. The Japanese attack on Pearl Harbor, Hawaii, was on Dec. 7, 1941.
A Biden spokesman said the candidate was referring to Delaware Day, an event celebrated on Dec. 7 since 1933 marking how Delaware became the first state to ratify the U.S. Constitution in 1787.
Although Biden has a reputation for making flubs on the campaign trail, President Trump, his rival for the White House, isn't immune to making mistakes. One example includes Trump saying in his 2019 Fourth of July address that during the Revolutionary War, the Continental Army, created in 1775, “rammed the ramparts and took over airports.”
Biden, 77, alludes to both Pennsylvania and Delaware as his home states. He was born in Scranton, Pennsylvania, but moved to Delaware with his family as a child, where he still lives with his wife, Jill.
