Each chamber of congress has the power to arrest ITS OWN members and compel them to attend a session of congress as provided for in Article I Sec.5 of the US constitution. The president does not have this power. The framers designed the constitution this way to maintain the separation of legislative and executive powers. The executive branch cannot compel congress to do anything, likewise the congress cannot compel the president to do anything. Its the principle of separation of powers. For reference here is Article I Sec.5:
Each House shall be the Judge of the Elections, Returns and Qualifications of its own Members, and a Majority of each shall constitute a Quorum to do Business; but a smaller number may adjourn from day to day, and may be authorized to compel the Attendance of absent Members, in such Manner, and under such Penalties as each House may provide.
