>Both houses of Congress pass a bill >President vetoes bill Congress __ Fill in the blank Holds protests at the White House Sends the bill to the Vice President to sign Enforces the law without presidential support Overrides the veto with 2/3 vote

## Step 1<br />The problem is about the legislative process in the United States. Specifically, it is about the situation where both houses of Congress pass a bill, but the President vetoes it. The question asks what Congress can do in this situation.<br /><br />## Step 2<br />According to the U.S. Constitution, if the President vetoes a bill, Congress can override the veto with a two-thirds majority vote in both the House of Representatives and the Senate. This is a check and balance mechanism to ensure that the legislative branch can still enact laws even if the executive branch disagrees.<br /><br />## Step 3<br />The other options provided, such as holding protests at the White House, sending the bill to the Vice President to sign, or enforcing the law without presidential support, are not constitutionally valid methods for Congress to respond to a presidential veto.
