The insider trading suspicions looming over Trump's presidency The BBC has found a pattern of spikes in trades ahead of public announcements by the US president.

🚨 BBC has examined trade volume data on several financial markets & matched them to some of Trump’s most significant market-moving statements.

It found a consistent pattern of spikes just hours, or sometimes minutes, before a SM post or media interview was made public.

In some South states, less than 30% of citizens have a passport, and most married women nationwide don’t have a birth certificate matching their current legal name.

Trump Pardoned a Nursing Home Owner Who Owed Almost $19 Million to a Grieving Family Stories about pardons are often about presidential power. But what about people on the other side of that grace? The Coulson family may never receive millions from a wrongful death lawsuit it won year...

Trump pardons those who can pay him which leaves those who hurt them with literally nothing. I can’t believe MAGA thought a billionaire would be on their side. #DV1 #ProudBlue #Voices4Victory #USDemocracy www.propublica.org/article/trum...

We had an excellent hike at a new place: Robbins Branch Trail in the Birkhead "Wilderness" in the Uwharries. We saw two cool new plants, one I'd never seen (Salvia urticifolia Nettleleaf Sage) and one I'd only seen 34 years ago, Senega officinalis (Seneca Snakeroot). Still new places to explore! 1/n

We filed suit against the Trump administration (again) today to block the implementation of an unlawful executive order that seeks to undermine inclusion & equal opportunity, threatens government contractors w/ criminal prosecution, & chills protected speech.

These are not normal times.
