He didn't forget that detail.
Those efforts got an unexpected boost on New Year's Day 2019.

Do you remember when child poverty fell to a record low in 2021 thanks to the expanded CTC?

It turns out that the SPM for kids was just as low in 2020 thanks to historically generous unemployment benefits. We missed it because UI is so under-reported in the CPS ASEC.
The figure includes three charts showing alternative estimates of the Supplemental Poverty Measure (SPM). The first figure shows the rate for everyone, the second for kids and the third for seniors. The estimates from a blend of survey and administrative data find lower poverty rates than those just based on survey data.
