Haley is now speaking live from Charleston, South Carolina, and she just announced she is suspending her campaign. There are now no major Republican candidates left running against Trump.

While you were sleeping, ABC News projected Trump as the winner in the last two presidential contests: Alaska and Utah. Trump currently leads in Alaska 88 percent to 12 percent and in Utah 57 percent to 42 percent.

After a full-ish night's sleep, we're back on the live blog as the winners of several House primaries from Super Tuesday remain unknown. However, the big news this morning is that campaign sources are telling ABC News that Haley will suspend her campaign for president after winning just one primary yesterday, making Trump the presumptive Republican nominee. She will deliver remarks at 10 a.m. Eastern, and we'll cover it live right here.

It's just past 2 a.m., and we've got major results in from most of Super Tuesday's wide-ranging slate of primary contests. So far, Trump has won at least 12 of the 15 states holding GOP presidential nominating contests, while Haley has won Vermont — though whether she hits a 50 percent (plus one vote) threshold of victory there will determine the exact number of delegates she takes home.

Either way, with an estimated 943 total delegates to Haley's 86 so far, per ABC News projections, Trump's well on his way to securing the magic delegate majority number of 1,215 — though it will take at least another week. He's so far secured 667 delegates tonight and is likely to hit the 769 mark that Elliott noted earlier would set him up to mathematically clinch the nomination on March 12. Of course, we're all watching to see if Haley drops out sooner.

In other highlights:

- As expected, Republican Lt. Gov. Mark Robinson and Democratic state Attorney General Josh Stein secured their parties' respective nominations, and will go head to head in what's expected to be a close general election contest for governor.

- Rep. Colin Allred locked up the Democratic nomination in Texas's Senate race, and will face off against Sen. Ted Cruz in the general.

- Democratic Rep. Adam Schiff secured not only the top spot in a top-two primary, but also a likely glide path to the nomination, as the second spot on November's ballot went to Republican Steve Garvey instead of a second Democrat.

We're still tracking a dozen-odd downballot races that have yet to be projected, and awaiting presidential primary results in Utah and Alaska, so we'll see you back here tomorrow ... er, later today, with more results and analysis!

In Los Angeles, voters will decide which candidates will face off in November for seven of its 15 city council seats. Arguably one of the most powerful city councils in the country, it's been riddled with scandal the past few years.

In 2022, leaked audio revealed then-City Council President Nury Martinez making racist comments in a meeting that included two other council members, which ultimately led to her resignation. One of the other members who was part of that conversation, Kevin de León, remains on the council after surviving months of protests, calls for his resignation (including from President Biden) and a recall attempt. Today he's running for a second four-year term against seven challengers, including two former political allies, state Assemblymembers Miguel Santiago and Wendy Carrillo. Santiago specifically has scooped up the endorsement of the key labor unions that once backed de León, as well as the Los Angeles County Democratic Party.

Overall, policing, affordable housing and homelessness are big issues in the city, the second largest in the nation, and how the council decides to handle those issues in the future could help set the tone for the rest of the country. Today's elections could help decide, in part, how progressive the council will be: In other races, business interests have been targeting progressive Councilmember Nithya Raman, and spending to bolster the council's only non-Democrat, independent John Lee, who faces an ethics probe and a more progressive challenger.
