MANCHESTER, N.H. (AP) — Republican Senate candidate Scott Brown says America is at a dangerous moment in history and the Obama administration seems unable to handle several global crises.

Brown is set to deliver the Republican party's weekly address Saturday and will spend most of it discussing homeland security. The former senator from Massachusetts is running against Democratic incumbent Jeanne Shaheen.

In a transcript provided before Brown's remarks, he says the border must be secured and the military expanded. He mentioned the fight against Islamic State extremists in Syria, unrest in Ukraine and this summer's war between Israel and Hamas in Gaza.

He says this is what the world is like "without American leadership."

He doesn't mention Shaheen by name but repeats a campaign staple: That she is a rubberstamp for President Barack Obama.
