David Brooks warns GOP: There is a powerful generation gap when it comes to Republicans, writes New York Times opinion columnist David Brooks.

“To put it bluntly, young adults hate them,” says Brooks, who is viewed as a center-right pundit. “It’s hard to look at the generational data and not see long-term disaster for Republicans.”

The Republican Party these days looks like a direct reaction against immigration, diversity and pluralism, but millennials and Gen Z voters live with difference every single day and approve of current demographic trends, according to Brooks. He says there is a conservative way to embrace pluralism that involves being optimistic and noting the deep strain of pessimism in progressive multiculturalism.

“My mentor William F. Buckley vowed to stand athwart history yelling ‘Stop!’ Today’s Republicans don’t even seem to see the train that is running them over,” Brooks adds.

GOP lawmakers mull blocking Trump’s Mexico tariffs: Congressional Republicans have begun discussing whether they may have to vote to block President Donald Trump’s planned new tariffs against Mexico, potentially igniting a second standoff this year over his use of executive powers to circumvent Congress, says a Washington Post report citing people familiar with the talks.

The vote could also end up blocking billions of dollars in border-wall funding that Trump announced in February when he declared a national emergency at the U.S.-Mexico border, says the report. It “would be the GOP’s most dramatic act of defiance since Trump took office.”

A Politico article says Senate Republicans spent much of Monday complaining about the president’s new threats to trade with Mexico and promising pushback in the coming days.

Oracle alleges secret job negotiations: Tech giant Oracle Corp. ORCL, +0.57% has provided new details to support its accusation that rival Amazon.com Inc. AMZN, +0.66% secretly negotiated a job offer with a then-Pentagon official involved in a $10 billion contract in which Amazon was a key bidder, says an Intercept report.

In a court motion filed on Friday, Oracle alleges that while the official worked on preliminary research for the Joint Enterprise Defense Infrastructure program in 2017, he was also engaged in a secret job negotiation with Amazon. The motion also alleges that the official did not recuse himself until weeks after verbally accepting the Amazon job, so he continued to receive information about Amazon’s competitors and participate in meetings about technical requirements, according to the report.
