Gladys Mae West obituary: mathematician who pioneered GPS technology She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition.

It’s been reported Homan took bribery money when he was recorded by the FBI accepting a bag full of $50,000 in cash.

"On December 2, 1783, then-Commander-in-Chief George Washington penned: “America is open to receive not only the Opulent & respected Stranger, but the oppressed & persecuted of all Nations & Religions.”1
 More than two centuries later, Congress reaffirmed President Washington’s vision by establishing the Temporary Protected Status (TPS) program. See 8 U.S.C. § 1254a (TPS statute). It provides humanitarian relief to foreign nationals in the United States who come from disaster-stricken countries. It also brings in substantial revenue, with TPS holders generating $5.2 billion in taxes annually. See Part VI.
Department of Homeland Security (DHS) Secretary Kristi Noem has a different take. [screenshot of tweet].

So says the official responsible for overseeing the TPS program. And one of those (her word) “damn” countries is Haiti. Relevant here, three days before making the above post, Secretary Noem announced she would terminate Haiti’s TPS designation as of February 3, 2026. See 90
Fed. Reg. 54733 (Nov. 28, 2025) (Termination).

Plaintiffs are five Haitian TPS holders. They are not, it emerges, “killers, leeches, or entitlement junkies.” They are instead: Fritz Emmanuel Lesly Miot, a neuroscientist researching Alzheimer’s disease, Dkt. 90 (Second Am. Compl. (SAC)) ¶ 1; Rudolph Civil, a software engineer at a national bank, id. ¶ 2; Marlene Gail Noble, a laboratory assistant in a toxicology department, id. ¶ 3; Marica Merline Laguerre, a college economics major, id. ¶ 4; and Vilbrun Dorsainvil, a full-time registered nurse, id. ¶ 5. They claim that Secretary Noem’s decision violates the Administrative Procedure Act (APA), 5 U.S.C. § 706(2), and the Fifth Amendment of the U.S. Constitution. The Government counters that the Court does not have jurisdiction, and, in any case, the Secretary did not violate the law.

Plaintiffs seek to stay the Secretary’s decision under 5 U.S.C. § 705 pending the outcome of this litigation. See Dkt. 81 (§ 705 Mot.). To decide their motion, the Court considers first whether it has  jurisdiction. It does. See Part II. It then considers: whether Plaintiffs have a substantial likelihood of success on the merits; whether they will be irreparably harmed absent a stay; and whether a merged balance of the equities and public interest analysis favors a stay. See Part III. Each element favors Plaintiffs. See Parts IV, V, and VI.

Plaintiffs charge that Secretary Noem preordained her termination decision and did so because of hostility to nonwhite immigrants. This seems substantially likely. Secretary Noem

has terminated every TPS country designation to have reached her desk—twelve countries up,
twelve countries down. See Section IV.A.2. Her conclusion that Haiti (a majority nonwhite
country) faces merely “concerning” conditions cannot be squared with the “perfect storm of
suffering” and “staggering” “humanitarian toll” described in page-after-page of the Certified
Administrative Record (CAR). See Section IV.A.3.a. She ignored Congress’s requirement that
she “review the conditions” in Haiti only “after” consulting “with appropriate agencies.” 8
U.S.C. § 1254a(b)(3)(A); see Section IV.A.1. Indeed, she did not consult other agencies at all.
See id. Her “national interest” analysis focuses on Haitians outside the United States or here
illegally, ignoring that Haitian TPS holders already live here, and legally so. See Section
IV.A.3.b. And though she states that the analysis must include “economic considerations,” she
ignores altogether the billions Haitian TPS holders contribute to the economy. See id.
The Government’s primary response is that the TPS statute gives the Secretary
unbounded discretion to make whatever determination she wants, any way she wants. And, yes,
the statute does grant her some discretion. But not unbounded discretion. To the contrary,
Congress passed the TPS statute to standardize the then ad hoc temporary protection system—to
replace executive whim with statutory predictability. See Section I.A.
As to irreparable harm, the Government contends that, at most, the harms to Haitian TPS
holders are speculative. But the Department of State (State) warns [screenshot]

Dkt. 100 (§ 705 Reply) at 20–21.4 “Do not travel to Haiti for any reason” does not exactly
scream, as Secretary Noem concluded, suitable for return. And so, the Government studiously
does not argue that Plaintiffs will suffer no harm if removed to Haiti. Instead, it argues Plaintiffs
will not certainly suffer irreparable harm because DHS might not remove them. But this fails to
take Secretary Noem at her word: “WE DON’T WANT THEM. NOT ONE.” See Section
IV.B.2.b.
Finally, the balance of equities and public interest favor a stay. The Government does not
cite any reason termination must occur post haste. Secretary Noem complains of strains
unlawful immigrants place on our immigration-enforcement system. Her answer? Turn 352,959
lawful immigrants into unlawful immigrants overnight. She complains of strains to our
economy. Her answer? Turn employed lawful immigrants who contribute billions in taxes into
the legally unemployable. She complains of strains to our healthcare system. Her answer? Turn
the insured into the uninsured. This approach is many things—in the public interest is not one of
them.
For the reasons below, the Court GRANTS Plaintiffs’ Renewed Motion for a Stay Under
5 U.S.C. § 705, Dkt. 81.

I've seen fossils in some remarkable places, but this takes the prize: the benthic foram Nummulites in the base of the Great Pyramid of Giza. These massive blocks were quarried from the Eocene Mokkatam Formation when a relictual population of woolly mammoths still lived on Wrangel Island.

Previously, the companies have limited their political giving to state politics.
