The Note: Trump vs. Republicans, his advisers and the DOJ

Who isn't worried about Donald Trump firing Mueller?

The TAKE with Rick Klein

As the possible targets of inquiries have broadened, so have the presidential attacks. The raids of Trump attorney Michael Cohen’s home and office cut close to the president’s business and personal interests, and Trump responded by saying he views the actions as “an attack on our country, in a true sense.”

The RUNDOWN with MaryAlice Parks

“Who’s your biggest competitor?” Sen. Lindsey Graham, the South Carolina Republican, asked.

Zuckerberg struggled to get answers out for each.

Basic questions suggested a knowledge gap between the senators and their constituents who use this tech every day. On the other hand, trying to put matters of modern computing, data, coding, and storage into policy-speak exposed how far behind current regulations may be.

“Everything we click on? Is that in storage somewhere?” Sen. Deb Fischer, R- Neb., continued. She did not seem to like Zuckerberg’s mealy-mouthed answer.

“I do not know,” Zuckerberg replied.

“There have been reports that Facebook can track a user’s internet browsing activity even after that user has logged off of the Facebook platform,” Wicker went on.

Zuckerberg politely said he would have to check and get back to him, but in doing so illuminated the extent of the unknown.

Overall, the day reinforced how unfathomably large the company is today, and how few questions it has been compelled to answer previously.

The TIP with John Verhovek

According to a new poll conducted by the Harvard University Institute of Politics, 37 percent of likely voters between the ages of 18 and 29 say they will "definitely be voting" in the midterm elections this year, a number that would significantly outpace millennial turnout in the last two midterm elections. Among those likely voters, 69 percent say they want to see Democrats in control of Congress, while 28 percent favor the GOP.

The same poll, which was in the field from early to late March, found that 72 percent of 18-to-29-year-olds disapprove of President Trump's performance in office, another sign that Republicans may face significant headwinds in winning over a significant portion of the youth vote this cycle.

But while Democrats may be celebrating those numbers, historically millennial turnout has remained low, especially in midterm elections. Just 21 percent of 18-to-29-year-olds voted in the past two midterm elections, according to data from the Center for Information & Research on Civic Learning and Engagement.
