Joe Biden is in his home town of Wilmington, Delaware, this morning, but will in the evening head to nearby Philadelphia for an unspecified political event.

The White House has not yet made public any details of that event, scheduled for 6.45pm, but the president has frequently traveled to Philadelphia during his presidency. It's an especially good investment of his time right now - Pennsylvania is one of the swing states expected to decide the election, and Democratic turnout in Philadelphia and its suburbs is expected to be crucial to determining if Kamala Harris can win.

Rufo, in his post, refers to six specific paragraphs from Harris' roughly 200-page book.

CNN reviewed several of the passages highlighted by Rufo and found that Harris and O'C. Hamilton failed to properly attribute language to sources.

Rightwing operatives are getting desperate as they see the bipartisan coalition of support Vice President Harris is building to win this election, as Trump retreats to a conservative echo chamber refusing to face questions about his lies. This is a book that's been out for 15 years, and the Vice President clearly cited sources and statistics in footnotes and endnotes throughout.
