While Congressional Democrats dominated headlines with their impeachment of President Trump - who was ultimately acquitted by the Senate, US intelligence officials were sounding the alarm that a serious illness was sweeping through China's Wuhan region.
The idea of the ABC reporting seems to be that a president who is being impeached shouldn't miss a beat in anticipating potential--not actual--disease threats. And the perpetrators of what was clearly a constitutionally fraudulent impeachment--indeed, an Impeachment Theater event--should bear no responsibility. In my view that will be a losing narrative, just as the Russia Hoax was. OTOH, it will require skill and determination to turn it aside.
Beyond that, however, another bit of context may be helpful. Apparently the CDC is saying that they were basically misled by the Chicoms and by the WHO. They thought that what was happening in China was another SARS-Classic event that, while serious, could be contained. While wrong, that was not a totally misguided assessment, given the history of past SARS outbreaks in China, from 2003 on. Thus they remained focused on the developing flu season. What CDC didn't yet realize was that SARS-CoV-2 was, in epidemiological terms, a decisive development over SARS-Classic that gave the new virus much greater potential for a pandemic breakout. The thinking at CDC reflected informed epidemiological thinking as found in Michael Osterholm's 2017 book, which classified SARS as a regional epidemic threat but new flu strains as potential pandemic threats--potential global threats.
Thus, Trump--besides being greatly occupied with all the resistance shenanigans and the Impeachment Theater throughout the months of the Covid19 buildup and breakout--from November, 2019, to the end of January, 2020--would have been receiving conflicting accounts of the novel virus: those from the IC and those from the CDC.
All that said, there is definite material of interest in ABC's reporting, mostly IMO with regard to what it tells us about China. Here are the opening paragraph's from ABC, which cover the essential details:
