Answer;
The Senate must approve many presidential actions.
Step-by-step explanation;
-The House of Representatives has the power to impeach a government official, in effect serving as prosecutor. It has the sole power to conduct impeachment trials, essentially serving as jury and judge.
-Additionally, the president nominates , and with the advice and consent of the senate, he or she appoints the ambassadors, public ministers, judges of the supreme court and other officers in the federal government. The senate can therefore approve or reject the presidential appointees to executive and judicial branch orders.
