Democratic National Convention live: Bill Clinton, Jill Biden, Alexandria Ocasio-Cortez speak

Joe Biden is making a big show of the Republicans who are supporting him over their own party's president. But how many are there?

Joe Biden's wife, Dr Jill Biden, opened up about the death of their son Beau in a moving address to the Democratic National Convention today.

Day two of the week-long convention also featured a speech from former president Bill Clinton.

And once again, the Democrats sought to elevate the voices of Republican figures who have endorsed Mr Biden over their own party's incumbent President, Donald Trump. Today it was General Colin Powell, a former secretary of state under George W. Bush, who got a prime speaking slot.

But it was Dr Biden who impressed the most, as she spoke about the grief she and her husband felt following Beau's death.

"After our son Beau died of cancer, I wondered if I would ever smile or feel joy again. It was summer, but there was no warmth left for me," she said.

"Four days after Beau's funeral, I watched Joe shave and put on his suit. I saw him steel himself in the mirror, take a breath, put his shoulders back, and walk out into a world empty of our son.

"He went back to work. That's just who he is. There are times when I couldn't even imagine how he did it, how he put one foot in front of the other and kept going.

"But I've always understood why he did it."
