OFF TO THE RACES: So it was Biden who spoke with Maureen Dowd
BIDEN: POLITICO reports that it was Joe Biden himself that leaked the account of his dying son's wishes for him to run for president. MORE: "At the end of August, while friends were still worrying aloud that he was in the worst mental state possible to be making this decision, he invited Elizabeth Warren for an unannounced Saturday lunch at the Naval Observatory. According to sources connected with Warren, he raised Clinton’s scheduled appearance at the Benghazi committee hearing at the end of October, even hinting that there might be a running-mate opening for the Massachusetts senator."
NBC's Alex Jaffe writes that the latest trade agreement is yet another policy hurdle for Biden's potential bid.
CARSON: He talked about his evolution on gun control in an interview with USA Today. "Reading people like Daniel Webster, who talked about tyranny in Europe and said it would never occur in America because the American people were armed," he says. "When you look at tyranny and how it occurs, the pattern is so consistent: Get rid of the guns for the people first so you can go in and dominate them."
CLINTON: Her first national cable ad will target the comments about the Benghazi committee made by Kevin McCarthy, NBC reports.
If you missed it, here are her fiery comments to Savannah Guthrie about the "partisan" panel.
Some of Hillary Clinton's allies think that her campaign is needlessly pouring resources into New Hampshire, a state that could be a lost cause, writes POLITICO.
Democrats are keeping the heat on Republicans on the House Benghazi Commitee, writes the Washington Post. "On Monday, Democrats on the special committee released portions of interview transcripts from Clinton’s chief of staff while she was secretary of state, accusing GOP leaders of selective leaks designed for political gain. The excerpts were more favorable to the Democratic presidential front-runner’s side of the story about the Sept. 11, 2012 attacks on the Libyan consulate. Democrats gave Chairman Rep. Trey Gowdy (R-S.C.) five days to respond to their accusations or else they planned to release the entire transcript."
FIORINA: She criticized the media after The Washington Post reported that it took her years to pay off campaign debts to her staff and contractors after her 2010 Senate bid.
O'MALLEY: Ouch. Only two percent of Maryland Democratic voters - his home state! - like O'Malley for president.
RUBIO: NBC's Perry Bacon Jr. writes that some mainstream Republicans are viewing Marco Rubio as the candidate most likely to come out on top now after Jeb Bush's stumbles.
The New York Times looks at what it would take for Rubio to capitalize on the moment.
He said on TODAY that gun control measures would have done nothing to prevent the Oregon shooting.
Here’s Benjy Sarlin on Rubio’s “confusing immigration answers.”
TRUMP: His campaign sent water bottles and towels to Rubio's campaign office in DC with a note reading "Since you're always sweating, we thought you could use some water. Enjoy!"
After suggesting that he could exit the race if his poll numbers slip, he insisted on CNN that he's given no thought to dropping out.
He's warring with Stuart Stevens now, too.
The AP explores how Trump is known -- but not necessarily loved -- in other countries around the world.
And around the country:
CONGRESS: Leadership elections delayed until Oct. 29
"Congress and the Obama administration are frantically seeking ways to hold down Medicare premiums that could rise by roughly 50 percent for some beneficiaries next year, according to lawmakers and Medicare officials," writes the New York Times.
John Boehner's move to delay some leadership elections means that House Republicans are facing a protracted fight for power.
OBAMA AGENDA: Another tough fight in Congress
The president praised the trade deal reached in Atlanta as an agreement that "reflects America's values," but it faces a tough fight in Congress, the Washington Post reports.
From the New York Times: "The American commander in Afghanistan, Gen. John F. Campbell, said on Monday that Afghan forces had requested the airstrike that destroyed a Doctors Without Borders hospital in the city of Kunduz, conceding that the military had incorrectly reported at first that the response was to protect American troops said to be under direct threat.
