There are several issues that can lead to a president calling a joint session of Congress. Here are a few examples:

1. State of the Union Address: The most common reason for a president to call a joint session is to deliver the annual State of the Union address. This is an opportunity for the president to inform Congress and the American people about the current state of the country, outline their legislative agenda, and propose new policies.

2. Major policy initiatives: If a president has a significant policy proposal that requires legislative action, they may call a joint session to formally present their plan to Congress. This can be done to garner support, generate momentum, and rally lawmakers behind the proposal.

3. Crisis or emergency situations: In times of national crises or emergencies such as natural disasters, terrorist attacks, or significant economic downturns, a president may call a joint session to address the nation and outline the government's response and necessary legislative measures.

4. Foreign policy matters: If a president needs to seek congressional approval for a major international agreement, declaration of war, or military intervention, they may call a joint session to make their case and gather the support of lawmakers.

To determine specific issues that might cause a president to call a joint session of Congress, it is important to follow news updates, listen to the president's statements and speeches, and stay informed about current events. The president's communication team and official channels will announce and provide details about a joint session in advance. News outlets, government websites, and social media accounts can also be reliable sources of information regarding any upcoming joint sessions of Congress.
