House Speaker Mike Johnson (R-LA) will attend former President Donald Trump’s rally at Madison Square Garden on Sunday, according to a source familiar with his schedule, as Republicans hope Trump’s outsize presence in New York will deliver them a House majority.

Johnson has made a point of appearing with Trump since becoming speaker in October. He was the highest-ranking official to attend the former president’s Manhattan trial in May and has repeatedly visited his Mar-a-Lago resort, most recently delivering remarks at a fundraiser there last week.
