How did American media miss the Kay Granger story?

I am actually shocked. How does a member of Congress disappear from the public eye for months, miss votes for months with zero coverage in the media -- and then resurface at an assisted care facility, while her staff is consistently posting on social media like their office hasn't been shuttered?

(Edit: She appeared in DC last month for a portrait unveiling. That brings up more questions for me, though.)

Even today, half the articles I see about it come from Indian news websites journalists/aggregators, and I myself was informed by large accounts on social media that happened to pop up on my feed.

It almost looks like the only people who were even looking into this were Forth Worth-area Republicans.
