Julián Castro said Monday that his 2020 presidential campaign must raise $800,000 by Oct. 31 — or it "will be silenced for good."

Why it matters: Castro's existential ultimatum follows a similar plea last month from Cory Booker, who pulled in $1.7 million in just over a week to stay in the race. If Castro is successful, other lower-tier Democrats may attempt to replicate their strategies to pull in quick bursts of fundraising to try to make waves in the crowded primary field.

President Trump on Saturday signed four executive actions to provide relief from economic damage sustained during the coronavirus pandemic after talks between the White House and Democratic leadership collapsed Friday afternoon.

Why it matters: Because the Constitution gives Congress the power to appropriate federal spending, Trump has limited authority to act unilaterally — and risks a legal challenge if congressional Democrats believe he has overstepped.
