That’s because of crappy press coverage. Search for the word “news” and her name, and you’ll see all kinds of activity. I saw references to VP Harris’ involvement in three events over the past week.
The MSM is always focusing on people more in line with corporate interest. They have no interest in informing the public about what the current administration is doing, to the point that Biden’s last major speech wasn’t even broadcast on the big three networks. However, that remark on the pandemic is everywhere, when 45 made far worse gaffes on a daily basis.

This morning, I even saw a report about Hurricane Fiona and the crisis in confidence among the residents of Puerto Rico after Hurricane Maria. However, it completely ignored who was in charge in 2017. That terrible response was par for the course during the rampant incompetence on display during 45’s administration. So, don’t expect coverage - we have to look for it, instead.
