Like Democrats under Joe Biden, they are planning to use the process that would allow them to approve bills on party-line votes, with a simple majority. 

The Senate infamously passed Biden's Inflation Reduction Act via budget reconciliation in 2022.  

Early priorities will be border security and reviving the tax cuts passed during Trump's first term. 

The president-elect wants the bill to pass the House and Senate, and be on his desk by May, just outside his first 100 days in office.

Republicans reportedly held a closed-door meeting at Fort McNair in Washington on Saturday, according to Fox News. 

While incoming Senate Majority Leader John Thune is prepared to use the process to pass two bills, Johnson may want it all done in one shot.

Thune has detailed a potential two-part strategy that would have senators working on an initial legislative package - energy, border security and defense priorities - that could be approved in the first 30 days of the new administration.

Next, Thune explained that the senators would turn to tax cuts - reviving the expiring tax cuts from Trump's first term - which is expected to take longer, dragging into the year.

Congress has not passed two reconciliation bills in one year since 1997. 

Republicans aren´t ready to eliminate the filibuster, which will make it harder to win some votes in the new 53-47 Senate.

The new Congress convened Friday, when lawmakers were sworn into office, and the Senate expects to quickly begin holding confirmation hearings for Trump´s top Cabinet nominees - some of whom are already running into resistance.

Republicans have had difficulty uniting around the details of their agenda, even when they control the levers of government in Washington.

But already fissures are developing over various tax and spending cuts, and broader policies such as Trump's plans for mass deportations of immigrants.
