Omar says she won’t ‘be silenced’ by search of her home and blasts Trump’s ‘intimidation’ campaign
Ilhan Omar called the search an “attempt to target political enemies and weaponize federal law enforcement.”
“For ten years, Trump has targeted me with baseless lies and smear campaigns.
This is just the latest escalation in his campaign of political intimidation,” she said.
“I will not be silenced.”
The search of the Minnesota congresswoman’s home
so close…
„Das eklatante Versagen des Verfassungsschutzes in allen schweren politischen Krisen der Bundesrepublik hat […] eindrücklich gezeigt, dass er schon mit den Machtmitteln, die er bisher erhalten hatte, nicht verantwortungsvoll umgehen konnte. Ihm neue in die Hand zu drücken, wo eine Übernahme der Staatsgeschäfte durch eine faschistische Partei kein unrealistisches Szenario mehr ist, würde den „Instrumentenkasten” der Demokratie vollends gegen Demokrat*innen richten.“
50 years ago tonight, the grateful dead in #SanFrancisco, their 2nd show of 6 at the orpheum. the band must’ve read fans bitching on social media about the lack of jamming the night before because things escalate quickly.

Abstract: Let $\boldsymbol{X}_i=(X_{1i},X_{2i})^\top$ be independent and identically distributed observations with mean $\boldsymbol{\mu}=(\mu_1,\mu_2)^\top$ constrained by $\mu_1\leq\mu_2$. We study empirical-likelihood inference for a fixed mean vector and distinguish it from the previously known test of equality against an ordered alternative. At a fixed interior point, the constrained empirical likelihood ratio has the usual $\chi^2_2$ limit. At a fixed boundary point $(m,m)^\top$, its limit is the chi-bar-square distribution $\tfrac12\chi^2_1 \tfrac12\chi^2_2$. By contrast, profiling the unknown common mean in the equality-versus-order test yields $\tfrac12\chi^2_0 \tfrac12\chi^2_1$, the $k=2$ ordered-mean case of El Barmi (1996). We give an exact reduction of the latter statistic to the empirical likelihood of the paired differences, establish the localization step needed for the fixed-boundary expansion, and derive a local-to-boundary limit showing that interior calibration is not uniform over $n^{-1/2}$-neighborhoods of the boundary. Monte Carlo experiments under Gaussian, Student $t_5$, and shifted log-normal sampling examine fixed, boundary, and local regimes with explicit numerical-failure accounting. Illustrative paired-data analyses show the practical distinction between fixed-candidate confidence regions, directional equality tests, and ordinary scalar empirical-likelihood intervals truncated to the nonnegative parameter space.

Car drives over book because it's too hard to stop and pick it up (or maybe the driver hates books, can't exclude that possibility), guy on bike picks it up because it's not hard. Big choices shape little choices.

‘Part of the fascist playbook’: Ilhan Omar condemns Trump DHS raid on her home
US Rep. Ilhan Omar on Monday forcefully condemned the
Department of Homeland Security’s raid on her Washington, DC home
as part of a broader effort to weaponize federal law enforcement
against progressives who oppose Donald Trump’s agenda.
“This is part of the fascist playbook

and give them a big distraction in advance of the midterm…
