'Start Here': Trump Jr.'s calls, Trump Sr.'s wall, sexual assaults in military spike. What you need to know to start your day. Blocked calls from Donald Trump Jr. went to family friends, sources said.

It's Friday, Feb. 1, 2019. Let's start here.

1. Trump Jr.'s blocked calls went to family friends

Mystery long surrounded three blocked phone calls Donald Trump Jr. made before and after the now-infamous Trump Tower meeting in June 2016.

There were questions of whether he informed his father about the controversial meeting, but now ABC News has learned the calls were between Trump Jr. and two family friends: NASCAR CEO Brian France and real estate developer Howard Lorber, according to sources.

Both men actively supported Donald Trump's 2016 campaign. A spokesperson for Lorber said the real estate executive "has absolutely not had conversations with Donald Jr. about any Russian matters."

ABC News' John Santucci and Matthew Mosk break down the developments.

"It doesn't actually prove anything, one way or the other, in terms of whether Donald Trump Jr. spoke with his father about the Trump Tower meeting or not," Mosk tells us. "They could've spoken in person, they could've spoken in other calls. It just means that these blocked calls, that there was so much suspicion about, weren't a lot of what the Democrats thought they were."

2. Walled in

President Donald Trump said on Thursday that any border security proposal without a wall "doesn't work."

Congressional negotiators have until Feb. 15 to come up with a deal.

ABC News Chief White House Correspondent Jonathan Karl says the president is also going back and forth on whether he agrees with assessments from his intelligence chiefs.

3. Sharp increase in sexual assault: Pentagon

An anonymous survey discovered that unwanted sexual contact at the three service academies spiked almost 50 percent last year, Pentagon officials announced Thursday.

ABC News' Luis Martinez says the survey also found that the number of incidents reported directly to authorities remained relatively unchanged.

"We do not believe the trends in this year's report reflect the time, energy and commitment dedicated to eliminating sexual misconduct from the service academies," said Dr. Elizabeth Van Winkle, executive director of the Defense Department's Office of Force Resiliency.

4. Cop who shot other cop was drinking on duty

Nathanial Hendren of the St. Louis Police Department is facing charges of involuntary manslaughter and armed criminal action in the shooting death of 24-year-old colleague Katlyn Alix.

Police initially called it an "accidental" killing in which an officer "mishandled a firearm." But investigators later determined that Hendren, who was on duty, and Alix, who was off duty, were playing a version of Russian roulette.

Hendren "recklessly discharged a firearm, resulting in the death of another officer" and "consumed alcoholic beverages while on duty," according to court documents.

Prosecutors are now suggesting police may have been too quick to call the shooting an accident, ABC News' Linsey Davis tells us.

Where did all the lopsided Super Bowls go?: On paper, Sunday's Super Bowl between the New England Patriots and Los Angeles Rams has all the earmarks of an instant classic. The teams are evenly matched in their strengths and weaknesses, and the favored Patriots' pregame chance of victory -- 52.8 percent, according to our Elo model -- is among the lowest of any favorite in Super Bowl history, meaning the game is close to a toss-up.
