From the Washington Post:
Kushner has emerged as an omnipresent and assertive player in the now-33-day impasse, despite deep skepticism on Capitol Hill about his political abilities and influence, according to more than a dozen Trump associates, lawmakers and others involved in the discussions.
Convinced that Senate Democrats will eventually crack and that there are votes for a bipartisan agreement, Kushner has urged the president to dig in while also adjusting his position as his popularity suffers in public polls, according to a person close to him and White House officials.
What exactly has he done? Kushner pushed for the idea of temporarily extending DACA protections for undocumented youth in exchange for the $5.7 billion Trump wants for his border wall, an idea that pleased no one:
After Trump spoke over the weekend, conservatives who are aligned with Trump’s immigration stance, from Rep. Steve King (R-Iowa) to commentator Ann Coulter, denounced the new proposal as “amnesty” and a political mistake. Democrats, meanwhile, rejected the offer before it was announced.
According to a senior Democratic aide, Kushner “is totally a nonentity” in the shutdown talks. One senior White House official, per the Post’s reporting, described Kushner’s positioning as “delusional.” Even Republicans like Senator Lisa Murkowski are dubious about his negotiating skills, with Murkowski noting that he “doesn’t have the experience” of Vice President Mike Pence.
Despite this, Kushner is hard at work in his “sparsely decorated West Wing office,” which includes, curiously, a poster of Kanye West above his door, possibly for him to stare at for inspiration.
