 # FPPC Behested Payment Scraper
 
-The FPPC has [a webpage to download behested payments](https://www.fppc.ca.gov/transparency/form-700-filed-by-public-officials/behested-payments.html) but the data seems delayed and doesn't have all of the behested payments. However, all of the payments do seem available by searching for particular politicans during particular years, such as [this one for Gavin Newsom in 2024](https://dv.fppc.ca.gov/Detail?Year=2024&Name=Newsom,%20Gavin). This script searches all officials who reported behested payments since 2011.
+The FPPC has [a webpage to download behested payments as an Excel file](https://www.fppc.ca.gov/transparency/form-700-filed-by-public-officials/behested-payments.html) but the data seems delayed, doesn't have all of the behested payments compared to other search tools, and has known errors.

+All of the payments _do_ seem to be available by searching for particular politicans during particular years, such as [this search for payments behested by Gavin Newsom in 2024](https://dv.fppc.ca.gov/Detail?Year=2024&Name=Newsom,%20Gavin). This script searches all officials who reported behested payments since 2011 and saves them to [`behested.csv`](https://github.com/CalMatters/fppc-behested-payments/blob/main/behested.csv).
+
+An example of a known error in the downloadable data is a $5,000,000,000 behested payment from the Waverley Street Foundation to California Volunteers in May 2024 though the FPPC's web tool for searching behested payments states that the value is $5,000,000, which makes a lot more sense and is used in this data set.
