Is it true the federal government reassigns each states share of seats in the house of representatives every two years?

No, the federal government does not reassign each state's share of seats in the House of Representatives every two years. Instead, apportionment occurs every ten years after the national census, which determines how many representatives each state receives based on its population. The most recent apportionment was based on the 2020 Census, and any changes to the distribution of seats will not occur until after the next census in 2030.
