Julian Castro raised $800,000 in the last 10 days of October, a fundraising figure that he said was necessary in order to continue his campaign, CNN reports.

Julián Castro on Monday threatened to suspend his presidential bid unless he can raise nearly $1 million by the end of the month, Politico reports.

Said Castro: “If I can’t raise $800,000 in the next 10 days — I will have no choice but to end my race for president. If I don’t meet this deadline, I won’t have the resources to keep my campaign running.”

Despite a claim made in a recent fundraising email, Julián Castro’s campaign manager told CBS News that the former Obama housing secretary won’t end his presidential bid if he’s unable to qualify for the fifth Democratic debate.

Julián Castro warned supporters that his presidential campaign will be over if he does not qualify for the November debate, the Texas Tribune reports.

“The email sought donations for ads to help him reach the new polling threshold: 3% in four national polls or 5% in two surveys from the first four early voting states. Castro has already met the donor requirement of 165,000 individuals but hasn’t met the polling requirement — or even come close.”

Julián Castro told CNN that his criticism of Joe Biden and his health care policy during Thursday’s Democratic debate was not personal and denied that he was attacking the former vice president’s memory.

Said Castro: “I wouldn’t do it differently. That was not a personal attack. This was about a disagreement over what the vice president said regarding health care policy.”

NBC News: “A poll released this week of national Latino voters had Castro, a former U.S. housing secretary and mayor of San Antonio, in fourth, with 45 percent… That was much better than Castro, the only Latino in the 2020 race, has fared in other polls on the Democratic primary race that polled fewer Latinos.”

New York Times: “Mr. Castro is in need of a breakthrough moment. Once considered a rising star in the Democratic Party — he was the first Latino to give a keynote address at the Democratic National Convention — he has been outshined in the ever-expanding field by brighter stars and nonstars alike. While he has many fans in his hometown, San Antonio, where he once served as mayor, he is not well known on the national stage. And with the sudden rise of the former El Paso congressman Beto O’Rourke, Mr. Castro is not even the most well-known candidate in his own state.”

“Still, during an interview at one of his favorite Tex-Mex restaurants, Mr. Castro seemed relatively unfazed, and maybe for good reason: At age 44, and as the only Latino candidate in the race, he would seem to satisfy the Democratic Party’s desire for youth and diversity, to say nothing of strategists who view Hispanic turnout as an important factor in winning back the White House.”

Politico: “Castro welcomed home-state colleague Beto O’Rourke into the crowded Democratic presidential primary field Thursday by releasing a list of more than two dozen elected and appointed Texas officials endorsing the former San Antonio mayor over the ex-El Paso congressman. The attempted show of force on O’Rourke’s launch day, however, may have fallen a little flat. The timing of Castro’s brushback pitch was viewed by some Democrats as unsportsmanlike.

“I don’t golf, so I’m going to work a lot harder than this president.”

“Texas Democrat Julian Castro, a former San Antonio mayor who went on to be the top U.S. housing official, was expected to formally announce his White House bid on Saturday, the first Hispanic in what looks to be a crowded field of candidates vying to challenge President Trump in the November 2020 election,” Reuters reports.

Julián Castro (D) convened a group of supporters in San Antonio in preparation for a 2020 presidential campaign, Politico reports.

“Castro and his twin brother, Rep. Joaquin Castro (D-TX), brought together about 20 of their loyal donors and bundlers in San Antonio to begin to sketch out a national bid.”

Julián Castro, the former San Antonio mayor and secretary of Housing and Urban Development, told Rolling Stone that he’s probably going to run for president.

Said Castro: “I’m likely to do it. I’ll make a final decision after November, but I’m inclined to do it.”

Castro is currently promoting his new book, An Unlikely Journey: Waking up from My American Dream, “the sort of get-to-know-me memoir widely seen as a prerequisite for a presidential run.”

Former Obama Cabinet secretary Julián Castro has formed a new PAC as he steps up his political activity and considers a possible run for president in 2020, Politico reports.

“Castro, long considered a rising star in the Democratic Party, has discussed his political intentions carefully, telling reporters that he will not run for office in 2018 but is not ruling out running for president… He is taking several preliminary steps associated with presidential campaigns; in addition to forming a political group, Castro is also writing a memoir.”

U.S. Housing Secretary Julián Castro said he is not being vetted to be Hillary Clinton’s running mate, the San Antonio Express News reports.

The former San Antonio mayor did not say who he thought would be a good pick for Clinton’s vice president telling reporters, “I’m not going to answer that,” and, when asked whether he’d gotten any phone calls from Clinton, he said “no, not at all.”
