The White House continues to work on a tax-cut plan in hope that Republican lawmakers will be in control of Congress after the 2020 elections, President Donald Trump’s top economic aide Larry Kudlow said.

“I am still running a process of Tax Cuts 2.0,” Kudlow said in an interview on CNBC Wednesday. “We’re many months away.”

Kudlow said the plan will released later in the summer, in time to be a campaign issue ahead of the 2020 election. Republicans are hoping to run on the message of a strong economy and draw comparisons with their Democratic rivals, who are proposing tax increases to pay for expanded government services.

Kudlow said the administration is getting guidance from Representative Kevin Brady, the top Republican on the House Ways and Means Committee who helped pass the 2017 tax cuts, which slashed the corporate tax rate to 21% and cut individual taxes. Kudlow has not been specific about what the latest tax plan could include.

Brady, who would likely be the chairman of the Ways and Means Committee if Republicans are able to re-gain a House majority, has said his top priority is to make the individual and pass-through tax cuts from the 2017 law permanent. Those tax cuts are set to expire in 2026, unless Congress takes action.

The success of Trump’s tax plan depends on Republicans regaining control of the House and maintaining a Senate majority. House Republicans would need a net gain of approximately 20 seats in the chamber, a difficult feat as unusually high levels of lawmakers from the party are retiring ahead of the 2020 election.

Trump made a similar promise to cut middle-class taxes before last year’s midterm elections as House Republicans struggled to counter Democratic talking points that the 2017 overhaul mostly benefited the wealthy. The president’s proposal caught Republicans off guard, and nothing advanced as Brady tried to cast it as part of a unified GOP plan to extend the 2017 cuts.
