New House total in effect following Green's resignation
Former Rep. Mark Green's, R-Tenn., resignation from Congress officially took effect on Monday, bringing the total number of members in the House to 431 -- 219 Republicans and 212 Democrats. There are currently four vacancies.
Speaker Mike Johnson, R-La., who announced the new total Monday afternoon, continues to have tight margins to work with to carry out Trump's agenda.
Republicans can only afford to lose three votes and still pass legislation, assuming full attendance and united Democratic opposition. This is the same margin as before.

The Republican Steering Committee will convene Monday evening to make its recommendation for a new Committee on Homeland Security chairman to replace Green.
