President Donald Trump's top intelligence officials will brief House lawmakers Wednesday on global threats facing the US - though they'll likely be questioned again over their use of a group text to discuss plans for military strikes in Yemen.

CIA Director John Ratcliffe, Director of National Intelligence Tulsi Gabbard and FBI Director Kash Patel are among those who were asked to testify before the House Intelligence Committee as part of its annual review of threats facing the US.

At a similar hearing on Tuesday before the Senate Intelligence Committee, Gabbard briefed lawmakers on her office's threat assessment, noting that China, Russia, Iran and North Korea continue to pose security challenges to the United States, as do drug cartels and transnational criminal organisations.

The presentations from top Trump appointees reflect Trump's foreign policy priorities, including a focus on combating the flow of fentanyl, illegal immigration and human trafficking, and are taking place as Trump attempts to work out a ceasefire between Russia and Ukraine three years after Russia's invasion.

Tuesday's hearing was dominated by questions about Ratcliffe and Gabbard's participation in a group chat on Signal in which they discussed plans to strike Houthi rebels in Yemen. The group included a journalist, The Atlantic editor-in-chief named Jeffrey Goldberg.

Gabbard and Ratcliffe have said no classified information was included in the messages, but Democrats have decried the use of the messaging app, saying that any release of information about timetables, weapons or military activities could have put US servicemembers at risk.

At Tuesday's hearing they asked Patel, who was not a participant in the text chain, if he would investigate.
