List four details of Henry Clay’s plan to end the deadlock over the issue of California statehood.

1. Clay proposed the Compromise of 1850, which consisted of several legislative measures aimed at addressing the issue of California statehood and other controversial topics related to slavery and sectional tensions in the United States.

2. One of the key components of Clay's plan was the admission of California as a free state, which would upset the balance between free and slave states in Congress. To compensate for this imbalance, Clay proposed the creation of two new territories – New Mexico and Utah – with the decision of whether to allow slavery in those territories left to popular sovereignty.

3. Clay also called for the abolition of the slave trade in Washington, D.C., and the passage of a stricter fugitive slave law to appease southern slaveholders and help prevent conflicts over the issue of fugitive slaves escaping to free states.

4. Additionally, Clay recommended measures to settle the boundary dispute between Texas and New Mexico, as well as to settle the outstanding claims of Texas in exchange for the federal government assuming Texas's public debt. These provisions were included in the Compromise of 1850 in an effort to appease Texas and secure its support for the overall plan.
