'Start Here': Another border wall battle, North Korea seen not heard, Ethiopian Airlines disaster kills 157 Here's what you need to know to start your day.

It's Monday, March 11, 2019. Let's start here.

1. $8.6 billion

Another budget fight over the border wall is brewing, with the Senate this week likely to vote against President Donald Trump's emergency declaration.

The White House today is planning to unveil details of a budget proposal that includes $8.6 billion for a border wall, a senior administration official told ABC News. That's roughly 50 percent more than the $5.7 billion Trump originally was denied, leading to the longest government shutdown in U.S. history, which cost the economy about $11 billion, according to the nonpartisan Congressional Budget Office.

"This," White House Correspondent Tara Palmeri says on "Start Here" today, "is a fight the president is not ready to give up."

2. What is North Korea doing/not doing?

With new commercial satellite images showing that North Korea may be reviving its missile program, does Pyongyang's first test launch in more than a year loom in the not-too-distant future?

Kim Jong Un, seeking additional leverage in nuclear negotiations, isn't trying to hide what's going on, ABC News' Luis Martinez says on today's podcast.

"The North Koreans want to be seen doing something like this," he tells us. "They want those trucks, they want those cranes, they want all of that to be detected by the satellites."

3. 157 dead

An Ethiopian Airlines flight, which lost contact with air traffic control just six minutes after taking off from Addis Ababa Airport, crashed and killed all 157 aboard, including eight Americans.

It's the second deadly crash for a Boeing 737 Max 8 jet in less than five months -- a Lion Air flight crashed after takeoff in Indonesia in October, killing 189.

It's too early to tell whether the incidents are linked, but "it was like deja vu all over again," ABC News Senior Transportation Correspondent David Kerley tells us.

4. Like Uber but for breaking up Big Tech

"It's time to break up Amazon, Google and Facebook," Sen. Elizabeth Warren, D-Mass., declared in a recent blog post.

The 2020 hopeful is proposing that tech companies making at least $25 billion per year should be classified as "platform utilities" as part of an effort to restore competitive balance.

"The idea," says Max Read, who covers technology for New York Magazine and joins us on "Start Here" this morning, "is to make sure that these fields are competitive enough that consumers can have some power over the companies themselves."
