Republicans have secured their monopoly on power in Donald Trump’s new Washington, retaining their majority in the House of Representatives, CNN projected Wednesday, after picking up seats in California and Arizona and ushering in a dramatic new era of right-wing populist rule.

Republicans held on to their narrow majority in the US House, giving Donald Trump and his party unified control of the elected branches of government and limiting potential curbs on the incoming president’s power.

With the GOP retaining control of the House, Trump will enjoy a trifecta for at least the first two years of his term.
