President Trump is powering Republican fund-raising

Mr. Trump’s campaign was not required to file a finance report on Thursday, because he is not up for election next month. But his fund-raising appeal trickled down to other committees that are directly involved in the midterms.

His campaign committees, which have raised a remarkable $106 million since his election, have transferred more than $22 million to the Republican National Committee, or R.N.C., over the course of the election cycle, according to the filings. And Mr. Trump’s campaign said it transferred another $3 million to the R.N.C. this week, which is not reflected in the filings, and planned to begin a $6 million television and digital midterm advertising campaign on Monday that will run through Election Day.

The R.N.C., in turn, has transferred nearly $10 million to the party’s congressional campaign arms, the National Republican Congressional Committee and the National Republican Senatorial Committee, according to Thursday’s filings. That doesn’t include another $3.5 million it reportedly transferred to each committee this month.

By contrast, the Democratic National Committee, which has lagged significantly behind the R.N.C. in fund-raising, has transferred only $2.4 million to the party’s House campaign arm, the Democratic Congressional Campaign Committee, most of which came this month.
